My apologies if its already been discussed.

I've run into this bug a number of times. Most recently this morning. Sometimes, when using Shadow Dance, my toon will run through walls to some other point on the map. For example, I was fighting the boss in The Fox Den. I did a shadow dance toward the wall by accident (lets ignore the targeting issue). My toon ran through the wall (and several other walls) all the way to the beginning of the map.
