TArray of UStaticMeshComponents doesn't hold objects after construction

I’m making a TArray<UStaticMeshComponent*> in my actor’s constructor. At the end of the constructor, it has 6 items.

But when BeginPlay() calls, it has one NULL item. What’s wrong?

in ShipEngines.h:

	UPROPERTY(BlueprintReadOnly, Category = "Engines")
		TArray<UStaticMeshComponent*> Engines;

in ShipEngines.cpp:

AShipEngines::AShipEngines()
{
	Root = CreateDefaultSubobject<USceneComponent>(FName("Root"));
	Root->AttachToComponent(GetRootComponent(), FAttachmentTransformRules::KeepRelativeTransform);

	for (int i = 0; i < 6; i++)
	{
		UStaticMeshComponent* EngineComponent = CreateDefaultSubobject<UStaticMeshComponent>(FName(FString::Printf(TEXT("EngineComponent_%i"), i)));
		EngineComponent->AttachToComponent(Root, FAttachmentTransformRules::KeepRelativeTransform);
		Engines.Add(EngineComponent);
	}
	//Engines has 6 items
}

void AShipEngines::BeginPlay()
{
	Super::BeginPlay();
	//Engines has 1 item, and it is NULL
}

Well holy ****. Turns out you can’t have an array called ‘Engines’. Renaming it to ‘ShipEngines’ fixed it.
