I know, it's frustrating. If this happened back in Iron Age, I'd simply uninstall the game and leave. Now in Atomic, with maxed planes and tanks, I'm committed. My iPad keeps crashing all the time too, causing me to lose troops. I keep hoping it's temporary, I keep hoping Nexon is working on it. But so far their support is denying any issues on their end.
What sucks even more is this penalty of losing all troops during battle even when it's obvious to any moron observing the match that the attacking side was about to destroy the defense. Nexon, I hope you're listening, if you handled crashes more gracefully (being able to restart the match instead of the troop penalty), you'd get a lot fewer of these posts from us, even if the game did continue crashing as usual. Please see this thread in suggestions:

Players shouldn't have to suffer for your mistakes.
