I don't know...I don't want to sound like a hater because I am not against plussing things if it is a good kind of change but The Mansion is a retirement home for the post living. The Ghost host explains this and how all the ghosts have flocked from around the world and different time periods to be there. What we are seeing is most of these iconic ghosts getting headstones and crypts more than ever. To be that is a step away from the safe haven retirement scaring for ghosts than anything.
Well, there are almost a thousand ghosts in the HM. Even if a dozen or two dozen of them have headstones and crypts outside (and therefore are "local" ghosts), that still leaves the vast majority -- well over 900 -- as being from around the world and different time periods...
