I have the current repeating issue that the A.I. seems to, for a lack of a better word, mentally bluescreen. They are about to do a task (deliver resources, get resources, eat food, go to sleep, anything honestly), and they just end up frozen in place in front of the building and start to slowly dehydrate to death. Picking up something to scare them and scatter them only works to scare them away, but they immediately return to the same spot and refuse to move again, alternatively that they are stuck in an animation but not getting anywhere. Checking each of their statuses, it either says that they're doing an activity (Delivering Resources, rowing but not getting anywhere in the water, Gutting Fishes, etc), or they're Doing Nothing.
