Has anyone else had a glitch where the game occasionally keeps generating prizes after you shoot a UFO?

Yes, I think this happens if you have not performed those 3 friendactions first.

Cause I saw the spaceship. Blew it to bits, and after that tried to tap on the mini-aliens. And instead I got rewards for blowing non-existing spaceships. I don't complain. I got atleast 5 gold trick or treat bags from 1 town alone :D

I had something like this happen to me, I tried tapping the UFO about 6 or 7 times until it finally blew up, then when I went to tap a alien, it fired my 2nd shot and I think I got a reward for it.....

Is there a special method of tapping the UFO's to blow them up??
