Skillful Sleep But Sim Just Eats Leftovers

I've had my sim unlock the Skillful sleep perk from the new DLC pack, but when I have my sim take a skillful sleep; their ghost version just eats all if not most of the leftovers in the fridge that's really meant for my sim's family. Sometimes, the ghost version of my sim doesn't go away, or vanish after my sim wakes up; they just continue to eat more leftovers in the fridge. I had about two ghost versions of my sim eating nothing but the leftovers in the fridge. They didn't gain any skill level either; just ate leftovers and made a huge mess in the kitchen of empty/stinky plates everywhere. I find this bug funny, but annoying because that also means that I need to throw away simoleons by having my sims cook more food for the family to eat when they all wake up. Please help fix this or at least put this on the laundry list for this to get done!
