Re: Some of my packs are corrupted
Navigate to your Sims 4 Packs folder which will be in the same install location as your Sims 4 app, typically the User/Applications folder. Trash the following folders:
EP01
EP02
GP02
SP02
Then go into Documents > Electronic Arts and move your Sims 4 folder to the desktop.
Open Origin, re-download those four packs, then launch the game, go into CAS and see if it's fixed. If it is then move your saves from the Sims 4 folder on your desktop into the newly created Sims 4 folder, then test the game again.
