The Black Crow Softlock

If you deal too much damage to The Black Crow, he will not pick up the bell and will go invulnerable.

He will never pick up the bell or switch states at all and will continue to attack you until you die. He will remain invulnerable indefinitely.

Relogging or switching characters does not resolve his broken state. You cannot portal out. You cannot leave in any way other than waiting out the instance timer or dying.

Also experienced the same issue. Same exact symptoms and workaround.

Reference number is 2,314,301,406

Happened to me, as well.

Just happened to me. This is the dumbest thing ever. Until this is no longer a possibility, we must be allowed to get out of a boss fight or just stop having invulnerable phases.

Unbelievable, I am on a corrupted Nexus I went out of my way to get to and because I did too much damage to him at the door he's now bugged and I can't target him or do damage or TP out. But of course he can damage me! What a waste of time this bug sucks big time! I paused it and tried to reply but nothing helps. Trying desperately to find a workaround...

The problem still exists. Can't believe GGG would combine invulnerability phases with inability to leave a fight.
