Pretty sure this happened when moving a poltergeist room, one of the ghosts did not return to inventory and are stuck in place floating around. They don't show up on my exhibit list, I can't select them, they do not highlight, dragging an expert to them does nothing. The announcer constantly says a spirit has escaped, and the guests will occasionally run around as if a ghost had escaped, I assumed this was normal at first so continued on, I'm on the 4th star of the stage now and its getting really hard to get anything done as all my staff are running about instead of doing anything.

I deleted the building they was in and they just appear outside now, placing a new building on top of them pushes them aside. Anyone found a fix for this?
