@ConnorProductive Please move your entire Sims 4 folder out of Documents\Electronic Arts and onto your desktop. When you launch the game, a clean folder will spawn with no content. Don't add anything to it yet; just start a new save and look around for collectibles. It's a good idea to let the game run for a sim-day or two, just in case it takes some time to spawn the items you're looking for. It's best to start the new save in summer, if you have Seasons, so you'll have the easiest time finding items.
If you still don't see any collectibles, please make sure all your packs have loaded correctly. You can check by using the pack filter in Build/Buy.
Please also let me know where you expect to see the items that aren't spawning.
