@emelvillejr I've had this too so I also lock the doors to specific Sims. Yesterday I had a child Sim take their breakfast to the parents bedroom and sit on the bed while the parent showered. So now that door is locked to her.
It can also help to set the table if you have Parenthood. They should eat at the table if its set. I also keep bookcases out of bedrooms if it's happening, because they take a book from one bookcase and go and sit near another.
It's random lots affected for me and it's funny because I'm on one of the Cottage Living lots now and it's happening and it also happened on this lot when I played a different household on it in a previous save game.
