When moving down the ramp with a pet in the bear pit area of permafrost, the pet will run upstairs instead of following you into the lower section. You can prevent this by walking backwards, but walking forward causes you to train yourself.

There are also two(three) mobs in this area that have some sort of issue blocking them from being in line of sight. The two marked with X are always out of line of sight when trying to cast, and from some places when trying to melee. The wolf that roams has line of sight issues only on certain places along its path.
