Bugged Boss "I had to let myself be killed."

Bug Report ID: #1079927437

"I had to let myself be killed."

"The boss in question, on the map in the phase before breaking the bell, had its health reduced down to the red mark shown in the photo, but it didn't drop any further.

It became immune to any kind of damage and didn’t trigger the bell-grabbing mechanic that this boss usually does.

Since it was impossible to kill it, I had to let it kill me, and because it's a map with zero respawns, I lost the boss and additional experience (level 90+).
