Been amazing pluging, 
but noticed one smaller issue that if using “Inclusive” as Blueprint Nativization Method, then project packing fails with error like:
UATHelper: Packaging (Windows (64-bit)): Cook: LogInit: Display: LogBlueprintCodeGen: Error: BP /Game/SaOKStuff/AI/DroneAI/DronePawnBP.DronePawnBP is selected for nativization, but it cannot be nativized because it currently implements an interface class (/Script/DonAINavigation.DonNavigator) that declares one or more pure virtual functions.
Will need to use “Exclusive” unless is it possible to make the interface class compatible with nativization?
Edit: Is it related to this ticket:
“It appears that the virtual function that returns a null pointer is the cause. If you change the function signature so that a null pointer is not returned the project can then be packaged successfully.”
