Re: Why aren’t my expansion, game or stuff packs loading in sims 4

@BananaBluey09  Definitely don't buy the pack a second time.  Instead, try restarting your computer and launching the game again.  Sometimes packs don't load properly the first time they're installed, for whatever reason, but rebooting and reloading usually fixes the issue.

If Cats & Dogs still doesn't show up, please go into the game files, located by default in Program Files (x86)\Origin Games\The Sims 4.  Look for a folder labeled EP04 (C&D is the fourth expansion pack released).  If you don't see the folder, you'll need to redownload it from Origin: open your game library, click on the Sims 4 icon, select More > Expansion Packs, find C&D on the list, and click Download.

If Origin thinks the pack is installed but it isn't, clear its cache, restart your computer, and look again.
