When adding a component to a Water Body actor it should still nativized to c++ if the blueprint nativization is set to inclusive or exclusive with the blueprint having Nativize enabled.

Steps to Reproduce
  1. In any project enable Water and Landmass plugins
  2. In project settings set Blueprint Nativization Method to Inclusive
  3. Create a new Blueprint Actor from WaterBodyLake
  4. Add a Box Collision component to the actor, save, and compile
  5. Package the project

Expected Results:
The blueprint actor is nativized and the project compiles successfully.

Actual Results:
Packaging fails with an Ensure condition "MyOwnerWorld [...ActorComponent.cpp] [Line: 1278]"
