Decorations not sticking to moving ceilings (GZDoom, UDMF)

[SMG_Man]

I have an issue where ceiling lamps aren't staying attached to the ceiling when it raises up. There is a room in one of my levels where all of the nearby ceilings raise to make a pit and reveal some more monsters, but the ceiling lamps stay fixed in placed, defying gravity. Is there a way to fix this without simply getting rid of the lamps?
