Hostile Dragons Disappear Ocassionally

[Xvareon]

• This is an ocassional bug that I have been able to reproduce on multiple ocassions.
• To reproduce: fight any kind of dragon, sometimes they just disappear mid-fight. No trace, not in nearby chunks. Just poof.
• These are naturally spawned and encountered dragons. Nests and Caverns.
• I do not have this issue with original Ice and Fire
• I am playing with other mods.
• No crashlogs since its not crashes
• The notable information I only have in my logs is "Client thread/Error: couldn't render entity, java.lang.NullPointerException:null"
• I am using forge 2860 (latest) for 1.12.2 and I am using 1.3.1 of inf: rotn
• I hope this issue gets fixed soon, I have a clue what's causing it and it may be the roost AI again.
• I get this bug more frequently on lightning dragons.

can you send the whole log file, preferably the debug.log

[Xvareon]

Unfortunately, the logs have been buried among the other logs. This bug is also not easily reproduceable but rest assured it really is there.

[Xvareon]

Will send the logs if it happens again

latest.log

Happened again as of this time, a t5 fire dragon inside a cave. The logs don't provide anything.

Can confirm its not the rendering error. For additional information, this happens mostly when dragons are knockedback, breaking blocks in the process while biting me, the player. Can't fully back up the scenario to consistently reproduce it.

[Xvareon]

Happened with t4 lightning dragon this time, while not breaking blocks but biting only

One culprit might also be the multipart system

Can confirm its not the rendering error.

yeah the rendering error seems to be from ancient spellcraft, possibly with entity culling
