I have run this dungeon multiple times this week and have had this boss reset 5+ times. The bosses leap all over the place and you're supposed to use the entire space but like half of the room appears to be a dead zone that makes the boss completely despawn and reset.
This completely ruined my +11 key.
I thought we were done beta testing BFA?
Same !@#$ happened in my 14 and we did time due to it really annoying....
