I'm using the NwN 2 building placeables, converted by The George, to make a "Ghost village". The destroyed buildings are spawned in the area "OnEnter" but if a player approaches a building they enter a trigger that changes it into it's non-destroyed counterpart. I was just surprised to find that the "CreateObject" function didn't work with door object types. It was always going to be tricky to make it function just like a normal area, I'll just have to make it as close as I can but choosing to enter a building that you know wasn't there a moment before probably shouldn't be that normal anyway.
