Mogu'shan vaults bug

[Versórius-hellfire]

So I did the raid for mount / achievements, I got to last boss and for some reason, I couldn’t activate it as it kept getting interrupted. I had this lightning surround me constantly, I had no debuffs or anything at all, and it wouldn’t go away.
So i ran outside the raid, I still had it, I couldn’t mount and it just not would not go, so I had to kill myself to get rid of it.

What is this exactly? First time It’s happened, obviously some sort of bug. Needs fixing.

Paragons of the Klaxxi are also bugged. Sometimes one dude Hiskas or w/e his name is comes down and is untargetable. You have to then reset the fight and run all the way back on your wheelchair class.
