List of mods I no longer have keep showing on startup
At first the problem was that when my mods were installed, I couldn't use in-game computers to buy stuff. Or so I thought. So, I got rid of all my mods and went back in. Except the game still showed...
@Mul2k6 It sounds like Sims 4 is using a different folder than the one from which you removed your mods. Here's how to find that folder:

The mods are likely still in that folder, and once you remove them and delete localthumbcache.package, you should be able to add the mods you actually want.
