Thank you for taking the time to write in. If I understand correctly you were concerned about a recent battle you died in to seemingly invisible enemies. As a player myself, I can certainly understand any frustration this may have caused and I will be happy to address the issue.
Sometimes if the servers and the connection to your device are poor, the synchronization between your device and the opposing players device may not be completely synced up properly. When this happens, on his device he may have already defeated you in battle, but due to lag, your device may not have caught up to theirs'. With the amount of data being synchronized between your device, the servers, and the devices of every other player, if your connection lags, or the device is incapable of running that amount of data at once, and the information is not able to load correctly, the battle might seem to end prematurely but to the other player the battle may have already been won by the opponent(s).
If possible, please attach any screenshots you feel would be relevant in demonstrating the issue, as that will be of great assistance as we investigate this further.
To take a screenshot on your iOS device (and most Android devices) press the power button (on the top right of the device) and the 'Home' button at the same time. Your screen will briefly flash to confirm it's taken a screenshot. Navigate to your Photos App and you'll find your screenshot there.
I really am sorry for any frustration this may have caused. I will be forwarding this issue to the Game Team to investigate any potential issues within the system to deter this in the future. Should anything else come up please feel free to open up a new ticket and we will be more than happy to assist you. Otherwise, thanks for playing and have a great day!
Regards,
