@6464646564644 and @vanessashoe Please find the Sims 4 folder the game is using with this in-game method:
https://sims4.crinrict.com/eng/2018/07/how-to-find-your-user-folder/
And list the entire file path here. You can write [username] instead of your username if you want, but please leave the rest of the file path intact.
@6464646564644 Please also let me know whether your computer runs Windows or macOS and whether OneDrive or iCloud, respectively, is running.
@vanessashoe If the file path you find with the above method doesn't match the location of your saves, you just need to move the saves to the correct folder.
