No sims, ghost town (sims 3)

@jamieptaylor  Don't worry about the extra questions; messing with a game folder is always a bit strange the first time around.

It sounds like you removed your entire game folder from Documents, launched the game, and adjusted the settings.  For the next step, and until further notice, you're leaving your old game folder where it is on your desktop.  Open the new game folder, the one that's now in Documents\Electronic Arts, and delete the same five cache files.  You should see something like this:

(Yes, that's macOS, but I don't feel like booting into Windows right now.)

If you don't see this in Documents\EA, that means your game folder is somewhere else.  Search for "deviceconfig" in a File Explorer window, and copy (crtl-c) and paste (crtl-v) the address into a post here, so I can see where it's landing.

If you do have the new folder where it's supposed to be, once you've deleted the five cache files, you can delete the Saves folder (highlighted) as well.  Then open your old game folder, the one you moved, right-click on the Saves folder in there, and select Copy.  Then open the new folder again, to the same place as above, and right-click and Paste your Saves folder.  Don't transfer anything else over, and don't install anything, again unless your glitched save takes place in a store or player made world.  (If you're not sure, just let me know what the world is called.)

Now launch your game again, and try to load your save.  Let me know how it looks, and we'll go from there.  You don't have to save your progress; this is just a test.
