Citadel Act 2 + Delirium = Bugged boss fight

Hey guys,
I wanted to report a pretty nasty bug :) If you're playing Citadel and face the Act 2 boss while Delirium is active, when you transition to the second phase — during the animation where you're lying on the ground in the sand — the friendly Delirium monsters can freely attack you, and you can't do anything about it :)

+1. Totally annoying af

Just had the same thing happening to me, so its been happening since 0.2 and not on a priority to be fixed. thanks GGG. honestly great patch btw, but this is pretty annoying.
