Hey guys,
We have a quick update in regards to a minor bug that was detected in Modern War for Android players.
For the upcoming World Domination event, you will not be able to hit "attack again" after battling any player. However, instead of hitting attack again, you can simply close it out and then select a person to attack and that should work.
Our developers are working to have this fixed with the next update, and we do apologize for any inconvenience this may cause you.
Thanks!!
