Sims Won't Leave Small Business

My sim has a small cooking school business attached to her house with the new Businesses and Hobbies pack. I have noticed that every time I close the business after running a class there is always one sim who won't leave and the option to "Send Home" or say "Goodbye" doesn't show up, so I can't even kick them out. This makes my sim sleeping take forever. Along similar veins whenever my sim does skillful sleep, the projection never does anything (if it even spawns at all) and then doesn't leave when my sim wakes up. I even had 2 projections haunting and and making a mess of stuff at once.
