Expansion Packs have mysteriously vanished. [SOLVED]

Hi! When I tried loading Sims 4 today every single one of the expansions and stuff packs had vanished (I have all of them). They're still the folder in the correct place where they've always been but none were showing up in-game and all the icons were greyed out. I have no clue how this may have happened as the game was running quite smoothly the night before with no crashing etc. I tried downloading and applying the latest Game folder which seems to have partially worked as now most of the content has decided to appear again except for Fitness Suff, Toddler Stuff, Cats and Dogs, and Laundry Day. Please help!!!  Should I re-install everything?? I'm not even sure how to do go about safely doing that because my brother installed all my current Sims 4 content except for the last patch and DLC which I applied myself. Thanks!

Delete your current Game folder and replace by recopy/paste the folder Game from Laundry Day.

Looks like it worked, thanks for your help!!
