I believe this is an issue with the combat routine. This issue occurs when setting the resthealth. If my characters' health becomes lower than the setting my character keeps running straight, eventually into a wall, until his health becomes full.
Same issue for me as well, is this an easy fix? I have tried two different combat routines with the same results.
Try using the attached KupoRoutine.cs, I had the same problem and I added a check for movement to the DefaultRestBehavior routine.
It's fixed for next version which should be out within a week hopefully. Been very busy trying to prep the new nav system and botbase.
