Yeah, this happens to me nearly every time I run the Fix Up Redirectors command on a folder in my project.
Once I’ve saved all the autos as “Untitled” over each other, the editor crashes with the fatal error:
Fatal error: [File: ..\Engine\Source\Runtime\TypedElementFramework\Public\Elements\Framework\TypedElementData.h] [Line: 276]
Element 'World None.None - ID: 5' is still externally referenced when being destroyed! Ref-count: 2; see above for reference information (if available).
This happens every time I do this. Unfortunately, this is a hard crash, so the bug report window doesn’t even show up afterwards.
