Re: Mods file got deleted (not by me)
@SalieG1
@puzzlezaddictis right. If you accidentally saved your game with mods removed, all your sims in that save will be naked and bald if they had CC clothing and hair. Unfortunately this is permanent on that save. You would have to manually re-outfit everyone. You'll need to be diligent in NOT saving when mods are not there. Personally, I don't even risk it. If I remove my mods/cc, I always play a NEW save to test it. So, if everyone ends up bald, it's no big loss.
But since your mods folder is empty, that's the reason why. The Resource.cfg file was recreated automatically when the game saw one didn't exist.
As to how this happened, I have no idea. The game won't do that. It never touches the mods folder, even during updates. It's a very common misconception that updates and patches will corrupt your mods. It's completely false. I've been playing since it was released and modding just as long and I've NEVER had the game corrupt mods.
Of course it never hurts to have a backup...
I'd recommend what @puzzlezaddict said. Run a search of your hard drives for "*.package" and see what turns up. If you just accidentally moved the folder (which is EXTREMELY easy to do), you'll find it somewhere.
