'Items Removed' Mods dissapeared

Hi! 😢

So I'm a total simmer, and I practically play every day. I played before I went on a trip, this was Jan 2. 10 days later I was back (Jan 7 was the update, as I read) and I run the game and a message popped up saying the following:

"

ITEMS REMOVED

One or more items may not be installed on

your computer or the Origin account that is

currently logged in does not own these items.

100 (I don't quite remember but it was around 100)

Build Mode items has been removed

"

I have 910 mod files. But none appear. I go to CAS and all my clothing and everything is gone. I check the files, they are there. I read forums but they all talk about some lamps.. I don't know which ones they are but I think the plumbob ones. If thats the case I never use them so that didn't affects anything. YES I restarted my game. YES I read what people said in the forums. YES I did clean the folder, run the game, and then put the files back. YES I tried deleting all my households then trying to start a new world. And YES I'm desperate. NO, NOTHING HAS WORKED YET! ☹️

If someone could help I'd appreciate it A LOT! 🙂
