While it was very amusing watching her run around like a chicken with its head cut off, and meant she didn’t cast anything, she would randomly run out the door and reset which caused us to have to redo the boss all over again. We were able to kill it our second go before she could run out of the room given she did it again, but it seriously needs to be fixed given the boss shouldn’t behave in that manner.
EDIT: This has become a consistent issue to where she’ll run around when she’s the last one standing, luckily its not too much of an issue as long as she doesn’t run out the door and reset the fight, yet it needs to fixed ASAP.
