Re: Cant figure what goes into my mod folder and what doesn’t.

@JoJoVanilla1211 Hi!  The Mod / CC files you download should have either .package or .ts4script file extensions.  Those go directly into the Documents / Electronic Arts / The Sims 4 / Mods folder.  There is also a Resource.cfg file that is automatically generated when the game starts, so if you see that just leave it in there. If you want, you can create folders to better organize these files, just make sure you only have one folder for each category; ex. if you have MCCC, you can make a folder labeled MCCC and put all the modules in one folder; if you have a bunch of living room cc, you could make a living room folder; etc.

Once you load a game, you also have to enable Mods / CC in the game settings (click the three dot game menu, select game options, select other, check the box to enable CC / Mods, and if you have script files check script mods allowed).  If you do have to enable mods / cc you will get a prompt to exit and restart.  If you have mods in the folder and enabled in the game, you should get a list of them when you open the game again.  

I don't quite understand what you mean about your saved data not being in the game.  Have you saved a game but you're not able to load it?
