CreateExport: Failed to load Outer for resource

I’m getting a lot of “CreateExport: Failed to load Outer for resource” warnings.

When Cooking it says “the files are corrupt”. I have backups, but when I go back to them it’s giving me the same warnings and errors.

I’ve open the backups on other machines (Mac and PC) and they work fine. But going back to my main workstation is no good.

The last thing that happened before the problem was a crash trying to record a sequence in Sequencer.

I’m on a Mac and this is a blueprint project.

Since 4.12 it’s been nothing but problems.

Any help would be appreciated.

Thanks

I fixed this by deleting the preferences for the version of the game I was working on and restarting the computer.

This also fixed a lot of other little nagging problems as well.

After encountering this issue I figured out a way to resolve it, explained here Failed to load Outer for resource on opening a persistent level - Blueprint Visual Scripting - Unreal Engine Forums
