I had a pawn with high animals + Animal Hater trait, since trait doesn't actually negatively impact pawn unless nuzzled by am animal I decided to ignore the fact. Problem arises when AH pawn generates a thought about animals, usually when they bond. It causes whole AI of the affected pawn to crash, all thoughts vanish, mood bar and all other need bars lock and stop dropping and pawn gets stuck inside a loop of last two jobs unless save is rolled back or trait is removed from save file and reloaded.


I'd suggest making Animal Hater incapable of doing Animals so the tedium of bugfixing could be avoided and since it fits the trait (because why animal hater should have burning passion for working with animals?)
