Isn't this exactly how it happened here?

I saw a similar bug in the game I'm playing with Delph right now, titled: Nuclear Powered Whales. (Sorry, I'm not tech savy so dont know how to get the video up.)

Brown attempted to send an Assassin at a Lt. in the same lane at the very last second before a Lt with drills arrived. Brown's queen was escaping in a different direction.

The assassin, still in that flickering/launch state, somehow slipped under the Lt., not hitting it in the lane, nor at the outpost. The assassin continued on unharmed, as did the Lt. The Lt. was able to then continue on and chase down Brown's queen, eliminating Brown.

I think the problem lies with the limbo/flickering state. The timings by which things are supposed to be happening are imprecise, and allows for results that shouldnt be possible.
