I used to use Anadius repacks for the sims 4, and never used it without the auto updater, can anyone explain to me how to get the newest sims 4 packs without redownloading my whole game and how to manually update the game please ?

I saw there's the full game + dlc on fitgirl but Idk how I could only get the dlc I need, instead of reinstalling everything over again, and I really want the latest royalty pack

Also, I've been using a cracked version of the game, never switched to the official one even after it became free, because I didn't want the auto updates that would break all my mods, I only updated my game when a new pack I wanted released, idk if it changes anything with the pirating process
