Same issue here, my previous save it's from eons ago, i thought i've failed trying to unlock the chest on azo's floor, but seems not related.
simply i avoided a couple of fights using grieving mother's charme on npc's and closing doors, but i can't manage to go upstairs and get out safely from the area.
that's because (as previously read) everyone is hostile, even the statue
please, make this fix soon and retroactive, ty.
