Unreal Editor for Fortnite
Assets
I logged into my UEFN map and every single Character Device that I placed is missing. Absolutely terrible.
Update your map.
Everything should have been where I left it.
All character devices are completely missing
UEFN
THIS SHOULD NOT BE HAPPENING EVER!!
Check the Fortnite Device folder, they are all probably gone like ours are.
Yeah what the heck. We had so many characters set up in our map and now all of them are gone 
I’m in same boat, it really frustrating I lost 1800 asset after update. I manage to figure out that is problem is the file being read-only for me keeps asking this /4/ZK/NBTUPFQL0LOY69XKW5W0WR.uasset’. Is the file in use or read only. I revert them back, but it keeps happening again and again. I don’t know what else to do.
I had the same issue. In my case the issue was cause due to using fab assets as referenced assets. I removed my fab assets and the issue resolved for me
I finally got the Revision Control to work again by Updating SSD drive also the NVidia drive and restarting the computer, it syncs my folder directory back to Revision Control. this stops read-only file for me. Hope this help you.
Yes, this was other issue of mine I had 5 mesh from fab, I test it by migrating whole project to new project and remove them. Once they were removed state of ready-only file was gone. Now having issue cannot save 
The status of FORT-725035 incident has been moved from ‘Needs Triage’ to ‘Needs More Info’.
Same here, nothing I have tried has fixed this issue with my map so far. Happens every time we push an update it seems like. Must be some ongoing bug because I can see a lot of people having this issue as of late. I am new to the UEFN scene, coming from Unreal but already it seems like there’s a lot of issues surrounding this topic. Hoping it gets fixed soon.
