■ Reasoning
On certain iOS devices, there have been cases in which the app forcibly closes or a portion of the screen goes black on the World Map or in the field after the iOS/iPadOS 26.4 update.

After investigating the issue, it was discovered that updating the OS for iOS/iPad-based systems increased their required memory (RAM), resulting in a deficit in memory required to run the application.
There are cases when a lack in memory (RAM) causes the game to malfunction, even if there is space remaining in the device's storage.

Efforts were made by the development team to reduce memory requirements within the application, but as the effects of the changes to the OS system requirements have left a large impact, the conclusion was reached that it would not solve the root of the issue.

We sincerely apologize for the great inconvenience to many of our players.
We thank you in advance for your understanding and cooperation.
