Doing a 25 naxx run today and on Instructor Razuvious I'm mind controlling as usual with some pug priest that has never done it. Now I explain the fight and everything to him and he says he understands. Starting the encounter mind soothe run in and MC. Do it and I start tanking him and calling out for when he should taunt etc. Though something weird is happening during MC. It randomly breaks and I have no adds on me or anything to cause the timer to go down etc. I was thinking it could be something with the other priest or quite possibly a bug?
Any insight will be helpful.
