Black Crow Invulnerable

The Black Crow becomes invulnerable during stages on tier 15 map, cant even use a TP to leave, just have to suck it up and die at level 90..

i have this issue to but at lvl 65 T1 map
not as bad as you but still sad because it is a lvl up map...

Same thing happened to me just now, trying to bug myself out to the checkpoint...

Having this issue as well sadly.

happened to me just now, T15 corruption nexus... lost about 3.5h, a lot of currnecy and a chance to cleanse the area. cool

Same thing happened to me.

Black Crow is not picking up the Bell after phasing as it should.

I'm facing the issue right now.

I found a way to go back to your map and lose only the boss, not the content of the map.
Here is what i did:
When you're stuck with the boss exit to character selection
Select another character (I guess he needs to be at endgame as well)
Go inside the map, you'll start at the beginning
From here you can clear the map if you want, except the boss of course.
Or, create a portal !
Exit to character selection
Select the option to go back to your hideout
Take the portal ! you'll arrive where the new portal is.

Maybe you don't need to do all of this and just select the option to go back to your hideout, it wont delete your portal, dunno.
