Polar bears AI is being weird.

Single Polar bears seem to not roam at all.

I've tested both on server and singleplayer. They just stand still and sometimes rotate in place but thats it. interestingly enough I went close to one with a bear cub and they both just walked away from me I think the mother's supposed to attack me when im near her cub.

They were just walking in a straight line and both paused when the cub grew up.
