This happened at the 21 chic apartments in Myshuno. Replaced original bed and different beds have the same issue. Sims at first were friends. Sim A is asleep. I tell Sim B to sleep he walks over and throws his hands up and shows sim a sleeping above his hand. Same happened when they become best friends. Same happens when I tell the other sim to sleep when her roommate is sleeping.
I"ve also reset the beds and that doesn't stop it. When I had them become romantic they were able to sleep in the same bed. This bug should be pretty easy to reproduce. Just get two sims who are friends or goodfriends and make them try to sleep in the same bed.
