Additional Notes

I have backed up this project many many times to revision control, but even the saves there have been deleted/are inaccessible. This project means a LOT to me.

Hey NotDriedLettuce,

There is one possibility

Having the Project Files inside a OneDrive backed up folder is a bit of an issue. It could be the reason
What UEFN changes is not often acknowledged by OneDrive, and sometimes it restores Deleted or Changed Content, which can cause issues.
Syncing to a different snapshot, becomes troublesome because, what OneDrive has restored is left in the Project Folder and conflicts with the newly synced content.

Make a new Folder outside of OneDrive, like C:\Fortnite Projects, open UEFN’s Editor Preferences and Add an Array Element to the Project Folders setting and point it to the new folder.

Then close UEFN and open Windows Explorer, make another folder like C:\TempHoldingFolder
Now go to the folder ../../Users/../../Documents/Fortnite Projects and move the entire Fortnite Projects folder to C:\TempHoldingFolder

Now Open UEFN and download the project, it should be getting saved into C:\Fortnite Projects
into a clean empty space.

Hopefully this does something, any projects that are not messed up can be moved from the TempHoldingFolder/Fortnite Projects to the new Fortnite Projects folder.
But if their content is unchanged from their last URC Check in, download them just incase.

Unfortunately didn’t work. Although i found a way to get into my project file. When i enter, i get 27 verse build fail errors, and my level file is non-existent, despite having the umap file in the project folder. Also, my 50 or so revisions are just not there. I really have no idea what has happened.

FORT-920980 has been created and its status is ‘Unconfirmed’. This is now in a queue to be reproduced and confirmed.

I’ve got some more info:

  • My umap file is present in my project folder, however i am unable to locate my level file in UEFN
  • Project size is still the same as before the issue (84%)

What is the contents of the MyProjectM.uefnproject file mentioned in the error message?
You can open it in notepad and pasted the contents here.

The text file is completely blank.

However I did find a backup version that i’d saved almost half a year ago - the text file has the exact same title (not sure if that could create problems), reading:

If your .uefnproject file is empty that means your project is corrupted. That file may never be empty. Was your harddisk full at any point perhaps?

Could you try restoring your old .uefnproject file and deleting the empty one and see if that allows the project to open?

Hey Wouter,

I have successfully managed to get my project loadable again. However there are now a few issues present:

  1. My environment isn’t showing up. Landscape and water volumes are not present upon loading project.
  2. Mass error messages on session startup:

I believe there are files i might’ve missed, but am unsure of what they would be.

It seems there may be more files missing / corrupted.

Have you used Unreal Revision Control and used the CHECK IN CHANGES button on the bottom right side of the editor when you were working on your project?

Yep, i just tried syncing to an older version and all the missing files have been restored. My map now works perfectly again - thanks so much Wouter!
