Ok, I am late to this too. This is what happened on my end.
I have a male firefighter and a female fairy. I moved them in, and all of the sudden neither of them could use the bed to sleep. The would just reset. I tried resetSim {name} and I am
use to using testingcheatsenabled true but I was getting annoyed with the fact that they couldn't sleep. Cheating does not bother me, but I do have custom content loaded and nothing is more
annoying than when you have to try to determine if it is a game issue or if it was something I downloaded.
I read this thread and what worked for me was evicting my household with the house and then bulldozing the old house. Just to be safe I moved them to a different lot, and now they are able to sleep
in their bed. I hope this might help someone else. Happy Simming!
