Ok, well cc alone shouldn't be making this happen... but just in case it is: remove your mods folder and delete the localthumbcache.package file from your TheSims4 folder.
Do a factory reset and then try your game again. If it is still happening, then at least you know all your cc is ok and you will have cleaned any minor glitches out of your game with the reset.
Remember not to save your game without the mods folder in or you will have to reapply all your cc to each sim!
Factory ResetIf this doesn't fix it, post back. Meanwhile I'm going to have a good look around to see if anyone else is posting anywhere about this issue.
There doesn't seem to be a bug report on this so I'm assuming it's a 'new' bug!
