@Lime_strawberry to you use Mods or CC? If you do, or did recently, you could test without them and the cache file mentioned below to see if any of the Mods/CC, or cache from them, may be causing your issue:
Exit the game. Move the Mods folder from your "The Sims 4" folder [Documents > Electronic Arts > The Sims 4] to your desktop (save it for reference) and delete the localthumbcache.package file in your “The Sims 4” folder. Then check in a new game save to see if this issue is still occurring. You can test without saving in order to identify which CC/Mods are causing the issue. Then remove or add updated version(s) of the Mod/CC causing the issue.
