iOS Version of Game Crashing

TerraArran

Crashed twice today. All in arena too, but only lost one match because of this, but still one loss because of the crash.

I confirm that the stability of the game on IoS is an issue on my Ipod5. I recently updated my internet cable connection to improve its speed but I've seen no sign of improvement. After some time, the game lags, then, finally crashes. Is it possible that servers are suffering from undercapacity at times?
