[4.8.3] Why is my UPointLightComponent not created?

Projectile.h

UPROPERTY() UPointLightComponent*			LightComp;

Projectile.cpp

AProjectile::AProjectile(const FObjectInitializer& ObjectInitializer) : Super(ObjectInitializer)
{
	...
	LightComp = ObjectInitializer.CreateDefaultSubobject<UPointLightComponent>(this, TEXT("LightComp"));
	...
}

void AProjectile::InitProjectile()
{
	if (LightComp)
	{
		...
	} else
	{
GEngine->AddOnScreenDebugMessage(-1, 50.0f, FColor::Red, "No LightComp!" );
	}
}

InitProjectile() is called from the weapon after the projectile is spawned.

The debug message is displayed indicating that there is no LightComp.

Why is CreateDefaultSubobject not creating the LightComp, and what do I need to do to get it to?
