No issues with first boss. But then I snapped Merektha down in .25 seconds. DBM recorded it as a kill and I got loot, but the objective, my Raid Info tab, and the Adventure Guide all show that the boss hasn’t been downed and the barrier at the tunnel to the next boss is still up so I can’t progress.
I tried resetting, relogging, and changing dungeon modes before re-entering. Nothing made any difference.
