Re: Mods not showing up despite trying everything?

Did you try going to Game Options then click other and Enable Custom contents and Mods, if you use script mods you should also allow that, apply, then restart?

If that does not work check for broken Mods. You can remove them and just add your Mods back in small bunches. Check after each bunch until you find the bad ones. 

Mods need to be checked with every new patch or they can cause issues.
EA does support using Mods and CC, but you use them at your own risk.
If your game runs well without your Mods and CC. you may need to check each one to find the one that causes problems, with every new patch.
Then you can contact the Mods and CC creators for updates or solutions to the problem with their creation.
Also, check the sims forum its a lot of help their for Mods and CC.

Hope this helps, I am not an EA employee I am just trying to help. So if it did help please grant XP points ty.

I had a similar problem, I just had to click enable cc and mods and script mods in game options and everything turned out fine. Just make sure to double check because I think settings go back to default whenever you reinstall the game....
