[PoE2] The Black Crow boss jumps out of his arena, breaks, map uncompletable

I accidentally teleported outside of the arena using lightning warp. The Black Crow then used his ability to jump after me and also left his arena. This appears to have caused a sequence break as he didn't break down the door yet. I got his health to about 5% while he had his 90% damage reduction during his RP and now his health won't go any lower, I can't cull him, and he won't come back into the arena. He's not even trying to fight me so i can't get him to jump back into the arena. I can't complete my map as a result. Please stop forced RP and just let me kill him

Exact same issue for me!
