App crashes only when the city is under attack – Grepolis - Divine Strategy MMO Review

The application crashes when your city is under attack. Once the attack is over, the application let you get in back. Do not know if it is biased or not but will see. If I see it happening regularly than the developer must need to fibs a way to prevent such occurrences.
