[Bug]: Steam singleblock machines sometimes stop accepting steam

[talchas2]

Issue Summary

I've had (low pressure) steam machines sometimes stop accepting steam. They keep running just fine until they run out of steam. None of these help: breaking and replacing pipes, using conduits instead of pipes (or vice versa), soft mallet, rotating/moving the vent. Restarting the game does not help, it does persist, though I don't see any relevant difference in /data get block that could explain it. Deleting saves/$foo/data/{gtceu,enderio}* with the game off and starting the game up again in case it was stored in the fluid net/conduit net info, didn't do anything.

Breaking and replacing the machine does help (until it breaks again, which takes a while). Presumably there's some data somewhere in the save that would at least show a difference (and I have a save kept around to look at), but I don't know how to get at it.

Reproduction steps

Sadly I haven't been able to get any sort of consistent repro for the working->broken machine transition. (I've tried a little in a testing world, and a little in a "just gt" instance)

This was on 0.10.5, but it has also now occured on 0.11.2 (and its updated GT version). I've also now seen GT pipe -> (thermal) steam turbine fail, and I think thermal steam boiler -> GT pipe fail as well. I should have checked to see if removing the pipe and replacing it with a conduit worked, but I didn't.

[MatthiasMann]

The issue seems to be "systeams:steam" - the machines need "gtceu:steam" - I don't think you can use the thermal steam boiler to make steam for GT.

[talchas2]

Hmm, that's not quite correct, systeams:steam works fine. However they don't combine despite what I thought I was seeing, so the problem at least most of the time is that I was trying to also use the much more efficient gt boilers as well, and getting weird behavior from trying to have two fluids in the same pipes/conduits/etc. According to my notes I had one where a machine was stuck with no steam of either sort in it, which this would not explain, but I don't have that one saved and maybe I copied something wrong in that case anyways (and maybe it was something like conduits locking to fluids, depending on what pipes I was trying to use at the time).

Updating systeams to 1.8.2 lets me unify the steam created into gtce:steam with kubejs/data/systeams/recipes/water_boiling.json, no idea if there's any issues with that upgrade though that might be more subtle than "immediate crash/kubejs error".
