Core Piety is Bugged

Unfortunately I do not know how to reproduce this bug.
What happened in my Core map is as following:
- damaged Malachai and triggered Piety;
- damaged Piety until she went on my side again;
- damaged Malachai until Piety changed sides again;
- I died while Piety was lowlife (maybe 1% hp);
- Came back into the map - Piety probably dropped to 0% while I was in my hideout;
- The event when Malachai impales Piety did not happen, Piety remained at 0% hp - she wasn't casting spells anymore nor was she was moving, she was effectively stuck;
- Could not complete the map as Piety was essentially invincible, thus making Malachai invincible too;

I didn't have time to screenshot nor type /bug as it was a particularly nasty Core map and I did not want to die twice (high level char, even if it was SC).

I had the same bug. Piety can't die and Malachai is immortal.

same thing happened to me.

Playing tripple incini-totem build. I died, totems continued to damage, piety reached zero life and didn't die.

I resurrected, portalled back in, and then she won't die, ran around like a chicken for 5 minutes with my totems blasting away at her and Malachai to no avail.

Same bug here. Core Piety couldn't die although she was at 0 health and so Malachai stayed invulnerable.

not a bug as far as i'm aware, if a boss/monster dies when you are not in the instance then you don't get credit, including drops, quest completion, and lab rewards

Same bug. I never even came close to dying. It's happening right now. I ran around for 5 min then decided to port back and check if there is a solution. 2nd time piety drops to 0% she doesn't change sides.

Seems like a bug to me.


PS: Problem seems to fix itself when you port back to town and come back. When I reentered the boss arena piety way moving and changed when I took down her ES and 1hp. Still, needing to port to town to finish the map seems like something that should be fixed.
