@guccmoney420 No worries about the delay; people test when they have time, and I respond when I see it. By the way, it's normal that you'd only have 5 .dbc files. They're bundled cc content, and the launcher only creates a new one when the one currently being used reaches about 200 MB. So depending on the size of your cc files, you can fit quite a lot into one .dbc file.
One quick thing to check is whether TS3 is reading the game folder it should be. This is simple: look at the last modified date on the file labeled deviceconfig. It should match the last time you launched the game. If it doesn't, you have a second game folder somewhere that TS3 is currently using. You can search in File Explorer for the word "deviceconfig"; each game folder will have exactly one. (This doesn't work on a Mac though, so let me know if you have one, and check iCloud storage for a second folder.)
If you do find a second game folder, please copy and paste the file path here. It will show across the top of the File Explorer window.
If TS3 is in fact using the correct game folder, pull the entire thing out of Documents\EA and onto your desktop. Open the launcher to spawn a clean folder, then copy dcdb0.dbc from DCCache in your old game folder into DCCache in your new folder. Delete the five cache files, and open the launcher again and see what items are listed. Then launch the game, load a new save, and check whether that cc appears. If it does, you can set aside that .dbc bundle—you've confirmed that it's working. Just put it somewhere else, out of the new game folder you're using to test.
Do the same thing for dcdb1.dbc, except change the 1 to a 0, or TS3 won't read it properly. (Delete your cache files before launching the game again.) This way you can check the .dbc bundles individually, and hopefully salvage most of them.
Let me know how it goes, and whether you still want to try to recover the missing cc. Otherwise, you can copy over the rest of your content into the new game folder. Do it in batches, testing each time to make sure everything loads correctly. Leave the saves for last, after you've tested everything else. Here's a list of all the files in your game folder, including descriptions of what you'd want to keep:
