Sims 3 Ghost issue... not wanting to have a playable ghost but...?

Curious... I finally got my ghosts to come out of the graves, but now I can only see one of them. Ralph has seemed to disappear. Sunny is ALWAYS out of her grave... I can mourn, read or change the inscription on the graves. I can't move them or pick them up (it says it's in use by the ghost) with the current sim. I have to use moveobjects on and move the graves in buy/build mode if I want to move them at all... Any clue what I can do? I want to try to get Sunny back in the grave, and I want Ralph around again! Thanks ahead of time (Don't be afraid to message me on here!!)
