I've seen this happen too many times. Someone is about to get their 50% mark, the last shot from (let's say an Archer Queen) is fired off. It's going to destroy a builder hut, and score 50%.
But the queen dies while the arrows are in mid-air.
What happens? The arrows die, too!
This can happen with wizards, archers, etc... That last shot is important. If it is fired before death, let it count!
And yes, I know, I always point out the tiny details.
A Note To The Cynics
I'm not objecting to failure. I handle it just fine. You might be thinking that a win, shouldn't have to count on such a small detail. But sometimes it does, and it just seems to make sense. Trajectories finish their path once they are fired.
