SomeBlueprint.uasset: Failed to load ‘/Script/Savior2’: Can’t find file.
Open the blueprint causing this warning then:
File => Refresh All Nodes => Compile
[HR][/HR]
It’s trying to save from a soft reference to an Actor that might not exist anymore or the reference became invalid.
This I can only help you if you mail a zipped copy of the Unreal map that causes this warning, so I can step through with a debugger.
I will try to add more meaningful warning message there, which is hard because the target object actually doesn’t exist.
