I have found that the game will occasionally crash when I am trying to deploy multiple gunners in battle. The battle ends immediately. After reconnecting, the log does not have any 'Share' or 'Replay' buttons. I'm very sad
I've had this problem too. It's been discussed in other threads and it's 1 of two causes, or both simultaneously. 1) a memory problem with some devices. And you would need to make sure PP is the only app open. 2) connection issues. Making sure your connection is strong and stable before attacking.
There can be occasional memory issues when using the Air. We suggest you reboot the device to completely clear the memory and don't run any other background tasks when playing.
