Doing nothing or attempting to enter turn 225 after entering the 223rd or 224th save will cause a crash. However, if you enter the 222nd round and enter the 225th round by automating, it will not crash. I hope the above information will help you solve the problem.

Operating System

Android

Additional Information

After exiting the game on the Android platform and re entering, you will get stuck in the game's startup interface and cannot enter the main interface. You need to exit the game again to re-enter. Although it does not affect normal use, it greatly affects the user experience.
