Fail to package with nativization.
cannot convert from 'USceneComponent *' to 'UBillboardComponent
User Reported Bug:
1. Create a Blueprint Class "BP_BasePlayerStart" with parent class PlayerStart.
2. Open the created BP Class, edit in full BP editor mode.
3. Add a variable to BP_BasePlayerStart, for example "TestVar" of type int, so that the BP class is different from the base class.
4. Enable inclusive Blueprint Nativization
5. Cook + Package the project.
