I had an odd thing happen. I don't know yet if it's the clothing in the magic set or the long sleep pants that is Master Suite.
I made a new Sim and his everyday outfit is the genie looking outfit and the turban from the magic set. His sleep outfit is the long sleep pants from Master Suite that have a dragon on one leg.
He turns sort of nude looking and has no hair. I took him into CAS and changed the sleep pants to something different and he was normal again. I haven't tested the magic outfit yet because I needed to do something else and haven't reopened my game again.
Normally I have a very glitch free game and I have all EPs and SPs installed.
