I had a custom SceneComponent that would break when a Blueprint inherited from a Blueprint that had my component. I was able to fix it by following that thread.

I wanted to attach a couple StaticMeshComponent to my custom SceneComponent.

Constructor:  
StaticMeshComponent1-\>SetupAttachment(this);  
StaticMeshComponent0-\>SetupAttachment(this);

OnRegister:  
Super::OnRegister();  
this-\>StaticMesh1-\>AttachToComponent(this, FAttachmentRules::KeepRelativeTransform);  
this-\>StaticMesh0-\>AttachToComponent(this, FAttachmentRules::KeepRelativeTransorm);
