I tried:
Run redirector fix up
Deleting 80% of my current level whats in there
Loading an empty level
Resolved all log containing: ‘LoadErrors:’
Resolved all log warnings: ‘LoadPackage: SkipPackage:’
Clear Source Files Cache - After each retry from above
@Flak any other things the developers shared which we could try? I found this in the v40.00 known issues thread.
