The problem seems to be that the construction scripts doubled up all the BlueprintCreatedComponents, so there are now 2 scene components(actually the same one duplicated) and now 2 child actor components. Only the second child actor component is found in the archetype map.
The component to archetype map contains the second (more recently created) ChildActorComponent, the scene component (which appears twice in the blueprintcreatedcomponent list) and a BillboardComponent.
