KSP Community Fixes

This plugin is a collection of code patches for fixing bugs and performance issues in the KSP codebase, and adding small QoL improvements. Entirely new features (especially those already covered by other mods) are out of scope, as well as patches that might alter the stock behaviors to minimize potential mod compatibility issues.

This mod is meant as community project, so feel free to propose additional patch ideas by opening an issue, or to contribute with a pull request.

Download and installation

Compatible with KSP 1.8.0 to 1.12.5 - Available on CKAN

Required and must be downloaded separately :

• HarmonyKSP : Download - Homepage - Available on CKAN
• ModuleManager : Download - Forum post - Available on CKAN

Installation

• Go to the GitHub release page and download the file named KSPCommunityFixes_x.x.x.zip
• Open the downloaded *.zip archive
• Open the GameData folder of your KSP installation
• Delete any existing KSPCommunityFixes folder in your GameData folder
• Copy the KSPCommunityFixes folder found in the archive into your GameData folder

Features

Individual patches can be enabled or disabled by editing the Settings.cfg file. To make sure your changes persist when the mod is updated, it is recommended to make them in a ModuleManager patch. Open the Extras\KSPCF_UserSettings.cfg.extra file in a text editor for further instructions.

While all KSP versions from 1.8.0 to 1.12.5 are supported, using the latest one (1.12.5) is highly recommended, as many patches only apply to the most recent KSP versions. When a bug fix patch doesn't apply to an older KSP version, this doesn't mean those bugs don't exist there.

User options are available from the "ESC" in-game settings menu :

Major bugfixes

• RefundingOnRecovery [KSP 1.11.0 - 1.12.5]
  Vessel recovery funds properly account for modules implementing IPartCostModifier. This bug affect stock fairings, cargo parts and many modules from various mods (part switchers and procedural parts mods, USI, Kerbalism, Tweakscale, etc).
• KerbalInventoryPersistence [KSP 1.12.2 - 1.12.5]
  Fix the whole kerbal inventory persistence system being inactive in KSP 1.12.2+. This cause multiple issues, like being able to bypass kerbal inventories mass/volume limits, and various cargo part duplication / disappearance issues when EVAing / boarding.
• RoboticsDrift [KSP 1.12.0 - 1.12.5]
  Prevent unrecoverable part position drift of Breaking Grounds DLC robotic parts and their children parts.
• DockingPortRotationDriftAndFixes [KSP 1.12.5]
  Make the stock docking port rotation feature actually useable :
  • Completely prevent unrecoverable position drift of children parts of docking ports.
  • Fix joint failure and phantom forces when a docking port pair is set to opposite extreme angles.
  • Allow tweaking the rotation in the editor and while not docked in flight.
  • Rotation can now be properly used in a robotic controller.
  • Remove the -86°/86° hardcoded limitation of hardMinMaxLimits, it is now -180°/180°.
  • Fix many issues and state inconsistencies.
  • An optional DockingPortExtendedRotation.cfg.extra MM patch extending rotation range to 360° is available in the Extras folder. Copy it to your GameData folder and remove the .extra extension to use it.
• AutoStrutDrift [KSP 1.8.0 - 1.12.5]
  Improves the overall physics stability when using autostruts and prevent autostrut induced deformations following vessel modification events (decoupling, docking/undocking, fairing separation...).
• ModuleIndexingMismatch [KSP 1.8.0 - 1.12.5]
  Prevent modules persisted state from being lost in existing saves/ships following a mod installation/uninstallation/update. Note that this won't handle all cases, but it massively reduce occurrences of that issue.
• PackedPartsRotation [KSP 1.8.0 - 1.12.5]
  Fix part rotations not being reset to their pristine value when a non-landed vessel is packed, resulting in permanent part rotation drift when docking and other minor/cosmetic issues.
• PartStartStability [KSP 1.8.0 - 1.12.5]
  Fix vessel deformation and kraken events on flight scene load, also prevent some kraken issues when placing parts with EVA construction.

Minor bugfixes

• StockAlarmCustomFormatterDate [KSP 1.12.0 - 1.12.5]
  Make the stock alarm respect the day/year length defined by mods like Kronometer. Fix the underlying AppUIMemberDateTime UI widget API to use the mod-provided IDateTimeFormatter if present.
• StockAlarmDescPreserveLineBreak [KSP 1.12.0 - 1.12.5]
  Stock alarm preserve line breaks (and tabs) in the description field.
• ExtendedDeployableParts [KSP 1.12.0 - 1.12.5]
  Fix deployable parts (antennas, solar panels, radiators...) always starting in the extended state when the model isn't exported in the retracted state. This bug affect parts from various mods (ex : Ven's stock revamp solar panels).
• DeltaVHideWhenDisabled [KSP 1.12.0 - 1.12.5]
  Hide the stock stage delta-v UI elements and navball extended burn info when DELTAV_CALCULATIONS_ENABLED and DELTAV_APP_ENABLED are disabled by another mod or in the KSP settings.cfg file.
• AsteroidSpawnerUniqueFlightId [KSP 1.8.0 - 1.12.5]

  Fix spread angle still being applied after decoupling symmetry-placed parachutes.
• CorrectDragForFlags [KSP 1.12.3 - 1.12.5]
  Fix the "panel" variants of the flag parts using a single drag cube, causing excessive drag for the smaller options.
• LadderToggleableLight [KSP 1.8.0 - 1.12.5]
  Fix for the stock "Kelus-LV Bay Mobility Enhancer" light being always active even when the ladder is retracted, and implements manual control of the light.
• ReRootPreserveSurfaceAttach [KSP 1.8.0 - 1.12.5]
  Disable the stock behavior of altering surface attachment nodes on re-rooting, a questionable QoL feature that doesn't work correctly, leading to permanently borked attachement nodes.

• NoIVA [KSP 1.8.0 - 1.12.5]
  Allow to disable IVA functionality and prevent related assets from being loaded, reducing RAM/VRAM usage and slightly increasing performance in some cases. Has a "use placeholder IVA" option allowing to keep crew portraits. This patch is disabled by default and must be enabled from the KSP "ESC" settings menu. It has no entry in the Settings.cfg file and require a restart to take effect. Do not use this option alongside IVA mods like RPM or MAS.
• DisableNewGameIntro [KSP 1.8.0 - 1.12.5]
  Disable the "intro" popups appearing in the space center, VAB/SPH and tracking station upon creating a new career game. Disabled by default.
• ToolbarShowHide [KSP 1.8.0 - 1.12.5]

  Add part actions for locking/unlocking resources flow state.

Performance tweaks

• SceneLoadSpeedBoost [KSP 1.8.0 - 1.12.5]
  Reduce scene switches loading time with large/modded saves by caching the current save in memory instead of loading it from disk.
• OnDemandPartBuoyancy [KSP 1.8.0 - 1.12.5]
  Prevent the part buoyancy integrator from running when not needed. Improves performance for large part count vessels while in the SOI of a body that has an ocean (Kerbin, Eve, Laythe...)
• FastLoader [KSP 1.12.3 - 1.12.5]
  Complete rewrite of the KSP asset/part loader : prevent GPU framerate limits from affecting loading speed, implement multithreaded asset loading (20% to 40% speedup depending on CPU & storage specs), provides an opt-in mechanism for caching PNG textures in the DXT5 format, also implements loading of additional DDS formats (see BetterDDSSupport patch in the API/modding tools section).
• PQSUpdateNoMemoryAlloc [KSP 1.11.0 - 1.12.5]
  Prevent huge memory allocations and resulting occasional stutter on PQS creation happening when moving around near a body surface.
• PQSCoroutineLeak [KSP 1.8.0 - 1.12.5]
  Prevent KSP from spawning multiple PQS update coroutines for the same PQS after scene switches and on other occasions, causing large performance degradation over time.
• MemoryLeaks [KSP 1.12.0 - 1.12.5]
  Fix a bunch of managed memory leaks, mainly by proactively removing GameEvents delegates originating from destroyed UnityEngine.Object instances on scene switches. Will log detected leaks and memory usage. Also seeSettings.cfg to enable advanced logging options that can be useful to hunt down memory leaks in mods.
• ProgressTrackingSpeedBoost [KSP 1.12.0 - 1.12.5]
  Remove unused ProgressTracking update handlers. Provides a very noticeable performance uplift in career games having a large amount of celestial bodies and/or vessels.
• DisableMapUpdateInFlight [KSP 1.8.0 - 1.12.5]
  Disable the update of orbit lines and markers in flight when the map view isn't shown. Provides decent performance gains in games having a large amount of celestial bodies and/or vessels.
• CommNetThrottling [KSP 1.12.0 - 1.12.5]
  Disabled by default, you can enable it with a MM patch. Prevent full CommNet network updates from happening every frame, but instead to happen at a regular real-world time interval of 5 seconds while in flight. Enabling this can provide a decent performance uplift in games having an large amount of celestial bodies and/or vessels, but has a detrimental impact on the precision of the simulation and can potentially cause issues with mods relying on the stock behavior.
• AsteroidAndCometDrillCache [KSP 1.12.5]
  Reduce constant overhead of ModuleAsteroidDrill and ModuleCometDrill by using the cached asteroid/comet part lookup results from ModuleResourceHarvester. Improves performance with large part count vessels having at least one drill part.
• FewerSaves [KSP 1.8.0 - KSP 1.12.5]
  Disables saving on exiting Space Center minor buildings (Mission Control etc) and when deleting vessels in Tracking Station. Disabled by default.
• ConfigNodePerf see also [KSP 1.8.0 - KSP 1.12.5]
  Speeds up many ConfigNode methods, especially reading and writing ConfigNodes.
• RestoreMaxPhysicsDT [KSP 1.8.0 - 1.12.5]
  When using physics warp, Unity will set the max physics dt to be at least as high as the scaled physics dt. But KSP will never restore it back to the normal value from the settings. This can degrade performance as it allows more FixedUpdates to run per frame.
• ContractProgressEnumCache [KSP 1.8.0 - 1.12.5]
  Prevent performance drops when there are in-progress comet sample or rover construction contracts
• DragCubeGeneration [KSP 1.12.0 - 1.12.5]
  Faster and more reliable implementation of drag cube generation. Improves overall loading times (both game load and scene/vessel/ship load times), prevent occasional lag spikes (in the editor mostly) and fix some issues causing incorrect drag cubes to be generated (notable examples are the stock inflatable heat shield, the 1.25m and 2.5m nose cones and the Mainsail shroud). Note that by design, this patch results in a small deviation from the stock behavior for buyoancy, aerodynamics and thermodynamics, as the generated drag cubes will be slightly different.
• LocalizerPerf [KSP 1.8.0 - 1.12.5]
  Faster and minimal-allocation replacements for the Localizer.Format() methods, can provide significant speedup for GUI-heavy mods using localized strings.
• DisableHiddenPortraits [KSP 1.8.0 - 1.12.5]
  Prevent non-visible crew portraits from being rendered after a switch back from the map view (and other cases), causing a significant perf hit when there are many kerbals in the vessel.
• IMGUIOptimization [KSP 1.8.0 - 1.12.5]
  Eliminate structural GC allocations and reduce performance overhead of OnGUI() methods. Can provide significant performance gains when having many mods using IMGUI heavily.
• CollisionManagerFastUpdate [KSP 1.11.0 - 1.12.5]
  3-4 times faster update of parts inter-collision state, significantly reduce stutter on docking, undocking, decoupling and joint failure events.

API and modding tools

• MultipleModuleInPartAPI [KSP 1.8.0 - 1.12.5]
  This API allow other plugins to implement PartModules that can exist in multiple occurrence in a single part and won't suffer "module indexing mismatch" persistent data losses following part configuration changes. See documentation on the wiki.
• DockingPortLockedEvents [KSP 1.12.2 - 1.12.5]
  Disabled by default, you can enable it with a MM patch. Fire GameEvents onRoboticPartLockChanging/onRoboticPartLockChanged respectively before/after calls to ModuleDockingNode.ModifyLocked(), following a modification of the ModuleDockingNode.nodeIsLocked field.
• OnSymmetryFieldChanged [KSP 1.8.0 - 1.12.5]
  Disabled by default, you can enable it with a MM patch. Change the UI_Control.onSymmetryFieldChanged callback to behave identically to the UI_Control.onFieldChanged callback :
  • The callback will only be called when the field value has actually been modified.
  • The "object" argument will contain the previous field value (instead of the new value).
• PersistentIConfigNode [KSP 1.8.0 - 1.12.5]
  Implement IConfigNode members marked as [Persistent] serialization support when using the CreateObjectFromConfig(), LoadObjectFromConfig() and CreateConfigFromObject() methods. Also implements Guid serialization support for those methods. Includes a complete rewrite of underlying ConfigNode code (in line with ConfigNodePerf) for performance, lower GC impact, and to fix some stock bugs.
• ReflectionTypeLoadExceptionHandler [KSP 1.8.0 - 1.12.5]
  Patch the BCL Assembly.GetTypes() method to always handle (gracefully) an eventual ReflectionTypeLoadException. Since having an assembly failing to load is a quite common scenario, this ensure such a situation won't cause issues with other plugins. Those exceptions are logged (but not re-thrown), and detailed information about offending plugins is shown on screen during loading so users are aware there is an issue with their install. This patch is always enabled and has no entry in Settings.cfg.
• DepartmentHeadImage [KSP 1.8.0 - 1.12.5]
  Fix administration building custom departement head image not being used when added by a mod.
• ModUpgradePipeline [KSP 1.8.0 - 1.12.5]
  This will save mod versions in sfs and craft files, and use those versions for mods' SaveUpgradePipeline scripts so that mods can handle their own upgrade versioning using native KSP tools instead of having to always run their upgrade scripts.
• BetterDDSSupport [KSP 1.12.3 - 1.12.5]
  Implement compatibility with the DXT10/DXGI specification, and support of loading additional texture formats :
  • BC4 : single channel (R) compressed 4 bpp
  • BC5 : 2 channels (RG) compressed 8 bpp
  • BC6H : 3 channels (RGB) compressed 8 bpp with HDR color range (Not available on MacOS)
  • BC7 : 4 channels (RGBA) compressed 8 bpp (Not available on MacOS)
  • R16G16B16A16 : 4 channels (RGBA) uncompressed 64 bpp
  • R16_FLOAT / R32_FLOAT : single channel (R) uncompressed 16/32 bpp
  • R16G16_FLOAT / R32G32_FLOAT : 2 channels (RG) uncompressed 32/64 bpp
  • R16G16B16A16_FLOAT / R32G32B32A32_FLOAT : 4 channels (RGBA) uncompressed 64/128 bpp

Stock configs tweaks

• ManufacturerFixes
  Fix a bunch of stock parts not having manufacturers, add icons for the stock "Stratus Corporation" and "LightYear Tire Company" and two new agents, "FreeFall Parachutes" and "Clamp-O-Tron".
• LandingGearLights
  Fix the lights on the "LY-10" and "LY-35" landing gears not automatically turning on/off when extending/retracting the landing gear.

Localization

This mod supports localization. If you wish to contribute a localization file, you can have the mod generate or update a language template by editing the Settings.cfg (see instructions near the end of the file).

Building

After loading the solution in your IDE, add a ReferencePath pointing to the root of your KSP install :

For Visual Studio, right-click on the KSPCommunityFixes project > Properties > Reference Paths, add the path to your KSP install and save the changes. Closing and re-opening the solution might be needed for the changes to propagate.

Alternatively, you can do that manually by creating a KSPCommunityFixes.csproj.user file next to the KSPCommunityFixes.csproj file, with the following content :

<?xml version="1.0" encoding="utf-8"?>
<Project ToolsVersion="Current" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
  <PropertyGroup>
    <ReferencePath>Absolute\Path\To\Your\KSP\Install\Folder</ReferencePath>
  </PropertyGroup>
</Project>

Then close / re-open the solution.

Building in the Debug configuration will update the GameData folder in your KSP install, building in the Release configuration will additionally create a zipped release in the Releases repository root folder.

For incrementing the version, edit the KSPCommunityFixes.version KSP-AVC file, changes will be propagated to AssemblyInfo.cs when building in the Release configuration.

The Start action of the IDE will trigger a build, update the GameData files in the KSP install and launch KSP. If doing so in the Debug configuration and if your KSP install is modified to be debuggable, you will be able to debug the code from within your IDE (if your IDE provides Unity debugging support).

• New KSP bugfix/QoL patch, LadderToggleableLight : fix for the stock "Kelus-LV Bay Mobility Enhancer" light being always active even when the ladder is retracted, and implements manual control of the light.

1.25.5

• Fixed issue #134 : fix for issue #133 was overly conservative, causing loading to stop on exceptions that don't cause a fatal error in stock.

1.25.4

• Fixed issue #133 : FastLoader allow the game to launch even when unrecoverable errors happen during loading.

1.25.3

• Fixed issue #128 : Fairing Expansion disable not retained after revert to hangar from launch
• Fixed issue #125 : Altimeter position was accounting for the AppLauncher width when using the settings slider, but didn't anymore after a scene reload, resulting in a slightly offset position.

1.25.2

• Fixed issue #96 : the AutoStrutDrift patch now correctly ignore autostruts originating from a servo part.

1.25.1

• CorrectDragForFlags : fixed flags in landscape mode using the same drag cube as for portrait mode.

1.25.0

• New KSP bugfix patch : CorrectDragForFlags, fix the "panel" variants of the flag parts using a single drag cube, causing excessive drag for the smaller options.
• Fixed issue #124 : avoid disabling the KSP-Recall "refunding" hack when the user has disabled the KSPCF "RefundingOnRecovery" patch, thus making our friend Lisias happy again.

1.24.6

• Fixed issue #121 : MapSOCorrectWrapping patch cause the Mohole to disappear

1.24.5

• Fixed issue #113 : FastLoader patch now requires KSP version >= 1.12.3 due to PartLoader implementation differences in previous 1.12 patch versions

1.24.0

• Updated for KSP 1.12.5
• New KSP bugfix patch : ChutePhantomSymmetry, fix parachutes in symmetry keeping their spread angle after decoupling.
• New performance patch : ContractProgressEnumCache (thanks to @abrenneke)
• New performance patch : FastLoader,Complete rewrite of the KSP asset/part loader : prevent GPU framerate limits from affecting loading speed, implement multithreaded asset loading (20% to 40% speedup depending on CPU & storage specs), provides an opt-in mechanism for caching PNG textures in the DXT5 format.
• The FastLoader patch also include a fix for issue #69, KSP bug causing loading hangs when an invalid *.png file is being loaded.
• TextureLoaderOptimizations : the patch has been depreciated, equivalent functionality has been integrated in the more general FastLoader patch.
• ConfigNodePerf : Fixed the Game.Updated() patch not being applied due to an AmbiguousMatchException when finding the target method.
• StockAlarmCustomFormatterDate : issue was fixed in stock so the patch doesn't apply to KSP 1.12.4+
• RoboticsDrift : the patch now only apply to KSP 1.12+, as prior KSP versions have minor differences in the robotics code ultimately causing various bugs when the patch is applied, see issue #72.

1.23.0

• New performance / KSP bugfix patch : RestoreMaxPhysicsDT (contributed by @JonnyOThan).
• Fix typo in Strategy's SendStateMessage where bold was not disabled after title (as part of StrategyDuration fix, since that is the only place it would be used in stock KSP).
• Fix bug in ConfigNodePerf where it did not properly early-out of parsing if the cfg file had an extraneous } (stock parser aborts in that case).
• Added Chinese localization (contributed by @tinygrox).

1.22.2

• Fix stock bug in SaveUpgradePipeline exposed by ModUpgradePipeline: the stock SaveUpgradePipeline blows up if an UpgradeScript does not apply to both sfs and craft contexts.

1.22.1

• Add KSPAssembly attribute to MultipleModulePartAPI as well, and add the KSPAssemblyDependency to KSPCommunityFixes just in case.
• Set AssemblyVersion to 1.0 and only increment AssemblyFileVersion and KSPAssembly
• Refactor FieldData.WriteValue for ease in use by other mods.

1.22.0

• New modding patch : ModUpgradePipeline (@NathanKell)
• Further improve ConfigNode performance. The tunable settings blocks have been removed since base performance is high enough now. They've been replaced by a single setting that enables not indenting save games and craft files on save, which offers a slight performance boost reading and writing and a fair amount of savings on disk. See KSPModdingLibs#90 for full details. Note that some of this rewrite is done via PersistentIConfigNode. (@NathanKell)
• Add a KSPAssembly attribute to the dll.

1.21.0

• New performance / KSP bugfix patch : PQSCoroutineLeak (issue discovered by @Gameslinx)

• New performance patch : ConfigNodePerf (@NathanKell)

1.20.4

• Restrict UpgradeBugs to KSP 1.12+ since it is compiled against the new combined editor class.
• New KSP bufix : MapSOCorrectWrapping (contributed by @RCrockford)

1.20.3

• New performance patch : FewerSaves (contributed by @siimav)

• New KSP bugfix : AsteroidInfiniteMining (Thanks to @Rodg88 for reporting).

1.18.3

• MemoryLeaks : Only remove GameEvent delegates owned by destroyed UnityEngine.Object instances if they are declared by the stock assembly, or a PartModule, or a VesselModule. Some mods are relying on a singleton pattern by instantiating a KSPAddon once, registering GameEvents there and relying on those being called on the dead instance to manipulate static data (sigh...). Those cases will still be logged when the LogDestroyedUnityObjectGameEventsLeaks flag is set in settings.

1.18.2

• Fixed MemoryLeaks patch causing KSC facilities upgrades being reverted after a scene change.

1.18.1

• Fixed AutostrutActions patch causing nullrefs on part duplication and generally not working as intended.

1.16.1

• RoboticsDrift : fix "Servo info not found" log spam originating from servo parts for which the drift correction isn't enabled.

1.16.0

• New KSP bugfix : EVAKerbalRecovery (thanks to @JonnyOThan for bug-reporting)
• FairingMouseOverPersistence : patch now only applies to KSP 1.10.0 and latter, as the field it relies on doesn't exists in prior versions, causing exceptions in OnLoad()/OnSave().
• Codebase cleaning pass, analyzers are now happy (or silenced).

1.15.0

• New KSP bugfix : ScatterDistribution (thanks to @R-T-B)
• New KSP bugfix : LostSoundAfterSceneSwitch (thanks to @ensou04)
• Fixed KerbalInventoryPersistence patch not being applied on KSP 1.12.3

1.14.1

• Fix KSPCF issue #39 : AltimeterHorizontalPosition patch causes state inconsistencies with vessel filters.
• Fix KSPCF issue #40 : UIFloatEditNumericInput patch breaking IR custom FloatEdit control. Don't alter the control prefab list, instead return our custom prefab on the fly in the KSP methods searching the prefab list.

1.14.0

• New KSP bugfix : PartListTooltipIconSpin (investigation efforts by @StoneBlue).
• New KSP bugfix : AsteroidSpawnerUniqueFlightId
• New QoL patch : DisableNewGameIntro
• New performance patch : PQSUpdateNoMemoryAlloc (investigation and fix by @Linx).
• Updated Harmony to v2.2.1
• Fixed multiple RoboticsDrift patch issues:
  • Improved general numerical stability by normalizing input/output Quaternions.
  • Fixed potential NRE spam happening after in-flight vessel hierarchy changes (ie, docking/undocking/decoupling...)
  • Fixed random child-parts-of-robotic-part displacement after timewarping/reloading (bug introduced with the changes made in 1.12.2)
  • Modded robotic parts whose servoTransform has a position offset relative to the part origin (either due to non-zero local position in the model hierarchy or a position offset in the part config MODEL{} node) are now unsupported. This mean drift correction won't be applied for them, and the stock behavior will apply. KSPCF will issue a log warning when unsupported parts are loaded in flight. Note that such a configuration isn't fully supported by stock either, and such parts will also have issues when manipulating their angle in the editor. And while I might find a way to fix this issue in the future, I strongly recommend mod authors to check/alter their models to ensure the servoTransform has a zero relative position/rotation from the model root. As of writing, this issue notably affect the BDB Skylab truss, the "More Servos" mod by @Angel-125 and possibly others.

1.13.2

• RoboticsDrift : fixed a rotation offset being wrongly applied to child parts of translation servos following the fix for issue #35 released in KSPCF 1.12.2 (see report 1, report 2)

1.13.1

• Fixed NoIVA patch causing missing part textures when the part reuse/share IVA textures (ex : SXT). Note that this change negate the loading time gains of the original patch, and might even cause a small increase (a few seconds) if KSP isn't running from a SSD.

1.13.0

• New modding patch : ReflectionTypeLoadExceptionHandler
• New QoL patch : ShowContractFinishDates, contributed by @NathanKell
• New QoL patch : NoIVA
• Added localization support
• Added tooltips to in-game settings

1.12.2

• RoboticsDrift : fixed issue #35, incorrect handling of non-stock servo parts having MODEL{} rotation/position offsets and/or a model hierarchy where the rotation transform has a position/rotation offset relative to the model root. Notably fixes incorrect behavior with the BDB Hokulani OCO-RT90 Truss Structure.

1.12.1

• HidePartUpgradeExtendedInfo : fixed wouldn't show extended info sometimes for regular parts.

1.12.0

• DockingPortRotationDriftAndFixes : fixed autostruts crossing docking ports not being disabled if only one of the port pair is rotation-unlocked.

1.11.1

• TextureLoaderOptimizations hotfix : was causing loading to hang on KSP 1.10 and 1.11 due to using an Unity method only available since KSP 1.12. Will restore compatbility latter, for now the patch is disabled for all versions below 1.12.
• AutoStrutDrift bugfix : fixed potential ArgumentOutOfRangeException.

1.11.0

• New bugfix : ExtendedDeployableParts
• New performance tweak : TextureLoaderOptimizations
• new Qol tweak : HidePartUpgradeExtendedInfo, courtesy of @NathanKell (see PR#29)

1.10.1

DockingPortRotationDriftAndFixes refinements :

• Fixed the stock implementation being unable to handle a rotating docking ports when it is the root part (was throwing exceptions and generally wasn't working correctly)
• Fixed another stock bug : having a rotationAxis other than "Y" result in the docking port still rotating around the Y axis. This bug affect the 2 "inline" stock docking port parts.
• Fixed KSPCF bug : parent port not being able to rotate after re-docking
• Fixed KSPCF bug : things were not working as expected when using a rotating + non-rotating docking port pair
• Fixed KSPCF bug : prevent rotation being available when about to dock or after undocking when the other docking port is "acquired" but not docked.
• Various performance optimizations

1.10.0

• New bugfix : DockingPortRotationDriftAndFixes. This patch contain several docking port fixes, and supersede the DockingPortLocking and DockingPortDrift patches, those patches have been removed.
• New bugfix : PackedPartsRotation. This patch is a generalization of a fix previously implemented in RoboticsDrift, and now cover all occurrences of that issue.
• New QoL patch : FairingMouseOverPersistence (suggested by forum user @dok_377)
• New mod API optional patch : OnSymmetryFieldChanged (thanks to @DRVeyl)
• New mod API optional patch : PersistentIConfigNode (thanks to @NathanKell)
• PartStartStability : fixed the patch causing an ArgumentOutOfRangeException on scene/vessel load in FlightIntegrator.Update(). As a side effect, this patch now make the FI first "valid" execution deterministic (will always be on the fourth FixedUpdate() cycle).
• RoboticsDrift : fixed incorrect handling when a robotic part is the vessel root part
• Prevent some patches failing with a ReflectionTypeLoadException when another plugin assembly fail to load (ex : the Sandcastle/EL integration assembly)

1.9.1

• RoboticsDrift : fixed (harmless) [RoboticsDrift] Servo info not found... log spam when toggling the locked state of a robotic part in the editor

1.9.0

• New bugfix : RoboticsDrift, see issue #13.
• New mod API patch : DockingPortLockedEvents (added for KJR, see related issue)

1.5.0

• New bugfix : KerbalTooltipMaxSustainedG
• Fixed (again...) some patches not being applied

1.4.2

• Fixed ModuleIndexingMismatch patch causing issues with modules dynamically adding/removing resources. Specifically, the patch was causing part resources to be loaded before (instead of after in stock) the PartModule.OnLoad() call when loading a ShipConstruct. This notably fixes RealFuel resources being lost when reloading/launching a craft file, but that mistake likely had consequences for other fuel/resource switchers mods (B9PS, Firespitter...)
