We sincerely apologize for the inconvenience we have caused. Previously, in the Steam version of the game, there were issues where missing audio files led to errors(This issue only affects users who are using the original Steam version of the game), so we pushed a minor update today. However, we have discovered that for users who have installed the complete version, updating through Steam overwrites the existing "normal game content," reverting the game back to the Steam version. We deeply regret this issue. If you have already updated the game, you can fix it by re-overwriting with the complete version game files. Please note that this Steam update will not affect your save data, so there's no need to worry. In the future, we will be more cautious with related updates to avoid such inconvenience (no further updates are planned).
