Hello,
I defeated Eonar in Antorus on mythic, on an alt and after completing it, I kept a debuff called “Feedback: Burning Embers.” It has stayed on me after the boss fight and prevented me from running the rest of the raid. Only way to clear it was to relog.
Edit: Another bug, after killing Imonar while he’s in his transition phase on the bridge, causes the winds to permanently push you off the platform. Only way to fix is to relog.
