I was making a map and tried to test by launching a session from within the editor, but I get an error saying “Failed to Validate for Staging”.
Checking the log it’s saying there are files that are refrenced but no longer exist.
I’m not sure if I’ve deleted something by accident or whatever but I can save the map just fine, it’s only showing this error whenever I try to test the map from within the Unreal Editor.
Normally I’d just delete these missing files…but I can’t delete them as they’re already missing…
Hello!
I have had this happen a few times as well.
What has worked for me is (ugh i hate saying this) turning off and on again
Close and restart UEFN/FNC. The UEFN project needs to relink and download the FNC resources/assets used in your map again.
Essentially I think the references get broken so when you try and play the island it does not know where to look for the FNC actors you used that are inside UEFN.
Does that make sense?
There is a lot of hidden magic happening behind the scenes with the new Ue revision control and part of it is making sure all the references are linked up so everything is communicating.
If anyone else has an official (Epic) response or if this is incorrect then please let me know. Cheers!
restarting did not help me.
Was able to test map a few hours ago. took a break, loaded up, now this.
Each time I try, it shows me different disallowed objects that are very much allowed…
Edit: The GameFeatureData did not have the correct Default Map set, Did not get the “This is not the Default Map” pop-up error. but after checking and changing, loaded in.
I’ve completely given up on it honestly. I did the dirty and attempted to delete a level (it warned me it was dangerous lol) after about 4-5 hours of loading to like 55000% or something, it was still broken and I ended up just completely deleting the file and reverting it from scratch…again…
Same Here. I’ve been creating a map for a long time, and now, suddenly I have the same error, with nosense. For example, it said that a campfire isn’t allowed. Scuse me, it was 10 seconds ago, are you kidding me? I hope the developers could help us and resolve this, please.
To anyone still experiencing this, as of now there is no official fix but adding back the files in the directory that shows up in the log should temporarily do the job.
I was also getting these errors in a new level after I chose ‘Save Level As’. What worked for me is deleting ‘GameFeatureData.uasset’ file from Windows Explorer and the newly created level file. After opening the project it showed me GameFeatureData.uasset is missing and gave me option to fix it automatically. It compiled the project from old version control and it started working properly (no more validation errors).
Note: I would suggest to take a backup of whole project to other disk partition so that your efforts will not be wasted if this doesn’t work for you.
i had the same problem. it seems it appeared when i tried to import animations and skeletons… i deleted those and now is working. when gives you the error press on “LOG” info near that error button. you will know what to delete
