HELP! Stuck in broken fight with Azmadi

I don't remember what part of the fight, but he just disappeared. The room is empty. I cannot leave -- I can't portal because it's the boss room, and I can't leave because the red invisiwall for boss fights is up blocking the entrance.

I log out (both to character screen AND by exiting the game) and back in -- it dumps me back in the boss arena.

I'm stuck. I can't die, there's nothing to fight, and no way to leave or progress.

I'm having the exact same issue....

I'm just writing to say I laughed a lot. What a prison xdd
