Pitch black sim and Sleep skills?

2 problems since downloading the hobbies and businesses pack. 

First, i just loaded in to the game and both my household sims are pitch black. One of the sim icons in the UI bar has gone back to normal now but the sim themselves is still wrong. (These are not sims that aged up with the known tooth issue).

Second, i used the new sleep skill mastery perk but the 'ghost sim' that gains the skills just never goes away? So my sim wakes up and her double is still there. I wondered if the issue would go away if i used the perk again but now theres just an extra ghost duplicate.
