Totem unable to target enemies next to walls.

Any enemies that are against the wall including doorways cannot be seen by the totems and thus will not cast their spell towards that direction (while being utterly useless inside o of doors). The totem can only hit those target if they use a spell that can still hit them while aimed at another target.

From the looks of it though, it seems related to the bug of being unable to target enemies next to walls with skills.
