Threading bug in scene capture component

void USceneCaptureComponent2D::CaptureSceneDeferred()
{
UWorld* World = GetWorld();
if (World && World->Scene && IsVisible())

{ // Defer until after updates finish // Needs some CS because of parallel updates. static FCriticalSection CriticalSection; FScopeLock ScopeLock(&CriticalSection); SceneCapturesToUpdateMap.AddUnique(World, this); }

}

The only thing that protects against is multiple calls to that function. I can do any number of bad things to SceneCapturesToUpdateMap in another thread causing crashes.
