Re: Sims 4 Growing Together Issues - still, four weeks later
@CheriBree Sorry for the late reply. There isn't any issue with the location of the game's installed files. You have one "The Sims 4" folder for the program files, which contains the EP13 folder, as it should. The other results in your search are normal for that pack: Delta contains the patch data, __Installer contains a record of the installation process, and the other entries relate to components of the pack itself plus some shortcuts Windows has created because you recently accessed that folder. (This is normal.) The Sims 4 folder where you've installed your mods, the one in Documents, is the user folder and has nothing to do with the game's program files.
Please go into the program files, the folder in your first screenshot, and delete the EP13 folder. Then clear the EA App's cache, again, and download Growing Together again. Then go in-game and let me know what content, if any, is still missing.
