I sometimes get this crazy targeting bug in raids. Mostly Tol Barad and AV. I run priest/dk's and quite often, when I mash my dps macro, my priest (main) switches from his target to some random pet mob. Then of course all the dk's try to assist. The mob could be halfway across them map and when i try to dps, i keep targetting that same dang mob. Never have this problem in a regular group. Also, this never seems to happen to the dk's. I can switch screens and use the dk's for assisting and such but then of course I have a useless tag along priest not healing or doing anything.

Anyone seen this bug? It's probably something with an addon but I just can't seem to find it. Really annoying bug.
