Game crashed seemingly without reason, game states this mod had issue with the wither witch from EnderZoo from what I can tell. The crash log.

Edit: I tried going right back into the world after posting this, it crashed again immediately as expected but this time a creature from Grimoire of Gaia was the one. Crash log 2 electric boogaloo

i no longer use Object2BooleanOpenHashmap. Update Soot.
