In my game post 1.69, every other bear is invisi-bear, in all areas. Fun part is, every other wolf is also invisi-wolf (only appears during the fight-scene). And even funnier part is every animal killed in every area sinks into the ground, taking an arrow with them forever. So all that is left is to hunt deer, which when not insta-killed and sink into the ground, beelines directly for the new small changes to the landscape here and there to get stuck in the geometry...and then sinks into the ground. I still see the birds on top of an inaccessible cliff, or half a bird flying around at ground level inside a rock.
