Sims wont sleep

So, I've been struggling with this issue for months and it's still happening! It started after the fairy update. I've tried almost everything! However, when I turn off mods that's the only time i can get my sims to sleep. I've tried TwistedMexi's Better Exceptions and I did find some mods that were messing my game up but it's still not letting my sims sleep. Does anyone have any idea how I can fix this??
