Fixed missing Traditional Chinese characters and text display issues.
Fixed an issue where defeating DLC bosses in previous playthroughs would not automatically unlock their soundtracks and gallery entries when starting a New Game+ (effective upon starting a new NG+ cycle; existing NG+ saves can unlock them by defeating the bosses again).
Added a return warp point in the K02·Alter challenge room of the Yidao stage, allowing players to exit without defeating K02·Alter.
