I was playing and a window with a message popped up stating there was something wrong with the game engine and gave me this information:
@stonehearth/components/ai/ai_component.lua:640: (3742 Alton Burlyhands) has not yielded after 10 ai spins. Are they in a bad state? Last abort reasons: <follow_path mover aborted reason: could not compute full path in start. (x10)>

Nothing seems to be going wrong. I could save normally, and the game is continuing to run. Sorry I can’t be more informative.
