How’s The Sims 4 Performance After the September 18th Update?

My game is running the same as it always did. About 6 months ago I noticed a much longer start up time, that hasn't changed. Lag has not been an issue. I did notice after a recent party I had several guest sims who refused to leave. I can't interact with them. They are just sort of standing there. One guys in his underwear which is a little strange. It was a costume party.
