Do you by chance play with custom content or mods if you do, you might consider going through them to see if something is interfering with your game.
I've come across this recently in my current game where I was using cc skin and my sim ended up with it. I quickly remedied that with taking that cc skin out of my game.
To fix mods and custom content try the 50/50 method:
1. Move all the mods and cc out into a temporary folder on the desktop.
2. Move a few files back at a time. Load the game to make sure it loads and everything is good.
3. Delete the localthumbcache.package from the Sims 4 folder.
4. Repeat steps 1 - 3 till there is no more files to check.
** While your testing, don't save the game. If you find any problems, delete the mod or custom content file.
