Derelict Mansion Boss Encounter Bug Report

+1 same bug. 3rd times it happens.
jucing ap with towers and 3 consantrated fear :Q just gone.

Still occurring to me.

Still bugged... sucks considering worst case you have to do like 3-4 maps without any node mods.

Still bugged, managed to kill the boss who played piano. But the lady kept dancing.

Same for me right now. GGG what in the world are you even doing?

Same here, no way to get fight started!

Same thing happening to me right now.

+1 same bug.

In my case, the other boss spawn outside of the battle area, and all the door is locked, make me unable to reach the boss.

This method help me.

On the Character Selection, click CLtr + Play. It make me appear on hideout. The portals to the map still there, -1 maybe because I brute force to leave the map.

Entering the map again spawn me in the one of checkpoint, and I can kill the boss after that.

+1 here, another bug...
