Ghosts Leaving Graveyard

I thought this was a glitch when I first noticed it.  My ghosts are getting in cars and riding off when they pop up in the graveyard at night.

I found a forum post about it, where others say that it's a function of Ambitions that goes with the Ghost Hunter profession: "Ghosts and spirits are wandering out of their graveyard and the catacombs."

It's not my favorite change, but I'm glad it's not a glitch.
