Attaching one component to another crash: 'template mismatch during attachment'

Hey try.

UPROPERTY(VisibleAnywhere, Category = "MyComponents")
TSubobjectPtr<UBoxComponent> SpawnBoxComponent;

AShipStart::AShipStart(const class FPostConstructInitializeProperties& PCIP)
    : Super(PCIP)
{
    SpawnBoxComponent = PCIP.CreateDefaultSubobject<UBoxComponent>(this, TEXT("Spawn Box"));
        if (SpawnBoxComponent )
        {
          SpawnBoxComponent->AttachParent = RootComponent;
          SpawnBoxComponent->SetWorldScale3D(FVector(200, 200, 200));
        }
}

That definitly should work. The question is, why UE4 engine supports so strange methods of attaching, if they meaning absolutely the same, but behaves differently…

I made some observations of UE4 code, and i think AttachParent is used mostly inside constructors, while AttachTo is not used inside constructors.
