@asianielle24 It's hard to say. You may have a corrupt save. Do you get the same errors if you start a brand-new save?
You can try deleting your cache files... Try deleting localthumbcache.package and try it again.
The "Items have been removed" is normal if you used CC in a house or sim and load the game without the CC installed.
If you played the game for a long while with mods/cc and then try playing it without those mods, a lot of weird things can happen. You should check for updates for your mods as well.
Try a new world for a while and see if you have any problems. If not, then I'd say there's a problem with that save. You can try deleting the cache files as I said, but I'm not sure there's much else you can do.
