Hotfix - Engine upgrade, data loss prevention — All Aboard! The Train Defense Express Steam update #956576

Hotfix Patch Notes First of all, we sincerely apologize for the recent issues that caused data loss and instability for a small number of players. We understand how frustrating even rare incidents can be and truly appreciate your patience and support. Changes: The game engine has been upgraded to Godot Engine version 4.4.1. This update includes numerous bug and crash fixes, significantly improving game stability. A new backup system has been implemented: Game statistics (experience, tickets, and levels) are now automatically saved after defeating each boss. If the game crashes, your most recent progress will be safely restored upon restarting. If you experience any further crashes, please report them in a reply to this Steam patch notes notification. Thank you again for your understanding and continued support!
