Thank you very much for your feedback and for letting us know about this issue.
It is possible that the problem may be caused by corrupted or unreadable characters in the save data .txt file, so we kindly ask you to check it.
Another possibility is that this bug may occur in non-Japanese system environments.
In the worst case, launching the game in Japanese might prevent the bug from happening.
We apologize for the inconvenience and greatly appreciate your patience and cooperation.
