Go see my dilemma when I tackled the issue of creating children of blueprints with components here: GenericMod Questions - ARK: Survival Evolved - Epic Developer Community Forums Both and I have to you if you want to change the components, until they change how children work, you must duplicate not create a child of that blueprint. Doing it this way allows you to entirely replace the components or modify them. You still can’t change the components with the blueprint graph but that is an entirely different issue.
