When we got to the rooftop, the Hungry Abberation fell through the ground and never got reset back to the rooftop, making it completely impossible to finish the raid. This has happened on other floors as well. There was one moment where we were supposed to open a door but the prompt to open the door never showed up. Something tells me this has something to do with co-op since I myself have never had any problems with enemies falling through the floor or missing actions. I took an image but I can't share it in the post for some reason.
