Sim won't sleep

The traveling didn't help, but the moving did the trick

I found that its often music or the tv going

Are you using mods in your game ? If so, try removing them.

This occurs for me on all pre-made houses by Maxis.

Sim's won't interact with a bed unless the whole lot is made by the player.

So, interacting with the bed is possible on non-Default lots but not possible on Default ones, whether you re-move back in or not.

I use mods, especially ones which heavily customize the game - but if it would a mod Problem I think the beds in General would stop working.

Figured it somehow out:

Could have been one of These mods:

• Woohoo is exercise  
• Teen Delivery - Teens Can Now Choose WHERE to Have a Baby
• Woohoo Acceptance Anims Replaced

It seems to be caused by mods which Change the animations when interacting with beds.

Now it's the fridge my sims won't use because something is in the way :/

EDIT (crin): Replaced Mod Links with mod names. Please do not link mods at AHQ

I saved and exited and came back in. That seemed to solve the problem. None of the other options seemed to work for me.

Going into Change Sim worked for me. I changed one of her outfits as soon as I came out she went straight to bed herself. 

I had this problem in Sims 4. I travelled to another sims house in a different world and put my sims to bed in their house. They had a full sleep then. Give it a try.
