Yes, I've been crashing for months. Daily. More than once a day. I have lost countless battles in every single category due to these crashes.
And I understand why a crash in the middle of a battle doesn't necessarily mean that the battle will reset. There are too many ways to force a crash, so people could take advantage and crash rather than lose. But, when I'm in a battle where I know I am about to WIN, and the game crashes, why should I be forced to take a loss? Can't the system run the battle on Auto, and award me a reasonable win, if that would have been the result if I stuck around? Why am I constantly being penalized for crashes that are not my fault?
This costs me, in terms of stamina, which is purchased with diamonds, and in opportunities to win in crypt and war and other areas. In war, at least I might get a retry, if I haven't used one already, but in crypt, if the system crashes I lose my line of heroes. No recourse.
