Can I delete these folders?
I'll have to paint a little backstory here: So i've been always playing on origin/ea app, but since i'm from Poland, the origin version fo the game only allows me to play in my native language, and...
@cheesegaiyke Yes, you can delete the Sims 4 folder inside Origin Games. When you launch the Steam install of Sims 4, the game data used is from the Steam install; the Origin install is completely ignored.
After you've deleted the folder inside Origin Games, restart your computer, clear the EA App's cache:

and then see if the missing packs will download this time.
By the way, the old Sims 4 folder is probably inside Origin Games because you originally installed the game using Origin. Installing the EA App doesn't change the location of already-installed games.
