         *  Game plan:
         *  1. Find the Level category
         *  2. Find the link with the Property SceneComponent
         *  3. Dig into the vanilla pak and the mod pak, try to find the connecting actor, add its nodes in the SimpleConstructionScript under BlueprintCreatedComponents (garbage1 = 0 no problem)
         *  4. Create the SceneComponent (garbage1 = 0), no RelativeLocation or UCSModifiedProperties, CreationMethod = EComponentCreationMethod::SimpleConstructionScript, bNetAddressable = 1
         *  5. Create the new Actor_C category, set its Linkage to the Level category, set the garbage1 to 0 (maybe random number idk), DefaultSceneRoot & RootComponent = the matching SceneComponent
