There is a bugged LFR instance, “The Dread Approach”, in MoP Remix Europe that needs attention. The instance keeps filling up, but the 2nd boss is bugged out so the instance cannot progress nor finish. I suspect it will keep luring people in till someone does a hard reset. Meanwhile, people are handed deserter debuffs for leaving the instance. Would be nice to have some quick attention to this.
Edit: I got a fresh instance now, so problem solved, thank you!
