Mods Folder Missing???

babytes  Is OneDrive running on your computer and syncing the contents of Documents?  If so, it may have removed the Mods folder from your system and stored it only in the cloud.  Please check your settings, and also look for your data on onedrive.com, both in My Files and the Recycle Bin.

If you don't use OneDrive at all, please let me know where Sims 4 is installed.  You can see it in the EA App, under Sims 4 > Manage > View properties.
