I discovered an issue in certain regions that use different numeric formatting standards (such as Germany, France, Spain, Italy, and others), where the game might incorrectly read configuration data, causing corrupted save files.
The root cause has now been identified and fixed. The problem was due to incompatibilities in how floating-point numbers were parsed under different regional system settings.
The issue is now fully resolved.
However, because existing save files may have been affected, players in the impacted regions may need to start a new game.
I sincerely apologize for the inconvenience and would like to thank the community members who helped me trace and confirm the issue.
I will continue improving regional compatibility to prevent similar problems in the future.
