Build fails when packaging a specific map that is not using an exclusively nativized blueprint

REGRESSION: Yes, in 4.17, the following warning occurs instead:

UATHelper: Packaging (Windows (64-bit)): Project.GetBlueprintPluginPathArgument: WARNING: Failed to find generated plugin for Blueprint nativization [C:\Users\mason.seay\Documents\Unreal Projects\MyProject3\Intermediate\Plugins\WindowsNoEditor\NativizedAssets\NativizedAssets.uplugin]. Nativization has run, but maybe there are no Blueprints which were convert
ed?

(See [Link Removed])

If the user packages a project with an exclusively nativized blueprint and a map select to include in a packaged build, the following error will occur:

ERROR: MyProject2 is configured for nativization, but is missing the generated code plugin at "C:\Users\mason.seay\Documents\Unreal Projects\MyProject2\Intermediate\Plugins\NativizedAssets\Windows\Game\NativizedAssets.uplugin". Make sure to cook Game data before attempting to build the Win64 target.

NOTE: This doesn't occur if there isn't a map select to package, but I don't get the warning above either.

1. Create and open a new code project.
2. Create a new actor blueprint and open it.
3. Drag off Event Begin Play and add a Print String node.
4. Compile and save.
5. Open Project Settings.
6. In Packaging, set Blueprint Nativization Method to Exclusive.
7. Add an array Element to List of Blueprint assets to nativize and set it to the blueprint you created.
8. Add an Array element to List of maps to include in a packaged build and set it to to FirstPersonExampleMap.
9. Package the project for Win64.

RESULT

Build fails with error.

EXPECTED

Build succeeds with warning (see description).
