game loading is in progress

@Momjob2005  Just to clarify, what often happens when you disable OneDrive's auto sync function is that the copy of Documents, with the Sims 4 folder inside, stays in cloud storage, not on your hard drive.  So when the game can't find that folder, it spawns a new one on your computer in Documents\Electronic Arts.

All you'd need to do to fix this is to grab the copy in OneDrive and put it back into your computer's Documents folder.  Or you can add the contents you want to keep (saves, mods, etc.) into the new folder in Documents\Electronic Arts.  But the point is, any content you want the game to read has to be there, not in OneDrive and not on your desktop or anywhere else on your computer.

If you're having trouble figuring out where the files should go, or why they don't work, please open a File Explorer window and find the Sims 4 folder that contains your Mods folder.  When you're looking at the contents of that folder, you'll also see the file path above the list of files, e.g. C:\users\username\....  Please list that entire file path here.  You can write "username" instead of your actual username, but leave the rest of the file path intact.
