I've noticed ever since pathfinding was fixed, a increase in people building "under construction" shelters or fences that let them pick off bears because they can get into the shelter but the bear cant, thus making them able to just pelt it with tons of arrows without much worries.
I am unsure how to combat this "perfectly", but giving enraged bears the ability to destroy fences/weak buildings when they lack a path to the player would be cool.
