Launcher -- UAV -- No reward

I see a UAV as Engineer and pull out my launcher. I ADS with launcher and try to find the right path. I proceed to fire after finding the right path and my missile disappears into the middle of the UAV. As I exit ADS the UAV explodes but I don't get rewarded the points for taking it down. Go to the 17 second mark on my video (sorry I am unable to cut video due to video editor being down). Observe the issue I am talking about.
