Black Cathedral bugged

I was in the Black Catedral for the abyss pinnacle boss, I managed to beat the first instances until he revived at full power, but then I died. Except after respawning, I was still there, and the boss revived in full power, however it's hp was wasn't displayed at the top. after exiting to character selection, I came back to the same situation but with the boss hp being displayed.
After dying a few times, I managed to kill the boss, but I died right after with the drops on the ground, and upon coming back, the boss is just dead and there are no drops anywhere.

Bumping this.

Charged boss up to full power and got stuck in the middle of the room. After dying, came back to Black Cathedral but the boss had no HP bar and was randomly teleporting me around.

same problem!

cant do this boss fight unless you kill it on first try otherwise no hp bar and cant kill him anymore

THIS. WHY was minions nerfed but THIS stays an issue?!

I'm having the same issue. Killed him at full power but died along side him. Now the zone is bricked. Every time I go into the well the Cathedral is open and if I go down the boos is just dead in the middle of the area. Even tried resetting the zone with a new finger in my inventory but it still the same. Please fix this GGG!!!

Same problem, we died at the same time and boss doesn't respawn nor I cant start new instance. It's just permabugged and I can't do this boss encounter anymore. -1 league mechanic I guess

+1

Bump

Just exit the instance and play something else for a while; it will reset eventually.

Same here, + I cant go back to my hidout, cant tp, fully softlock...
