Hello, Welcome to the Forums. First I’d check that your level is not in your content browser any more. (You can filter to see just levels if you want) ![filter_level](https://d3kjluh73b9h9o.cloudfront.net/original/4X/a/e/a/aea25356901f11f33abfd17307aca4f4b7b4b749.jpeg) As far as reverting to a “backup” - You would need to have been using the [Unreal Revision Control](https://dev.epicgames.com/documentation/en-us/uefn/unreal-revision-control-in-unreal-editor-for-fortnite) system. (Where you’d have checked in your project to revision control at some point in the past) ---

I think i can`t rewind it anymore cause it said that it had to sync with my map then i pressed the button to sync it and then I entered my project and everything was gone ![Bild_2025-01-08_220731941](https://d3kjluh73b9h9o.cloudfront.net/original/4X/b/8/f/b8fb24fd7e24b6e9054f9447a788fba7915b89db.png) It´s in German but it basically says that this Project is supported by Unreal Revision Control and that it will sync it with my Computer. ---

You would have needed to ‘Check in Changes’ (Which would have uploaded your project to the revision control servers) at some point before your map disappeared. Another thing I just thought of - Make sure your UEFN project is not in a folder that’s managed by OneDrive/Dropbox/GoogleDrive (any sort of real-time external file backup is inadvisable for UEFN projects) ---
