This is primarily for the new Chinese players but does affect any version of the game.
If you are experiencing save data not working in windows, it may be because your username on your PC contains non-ASCII characters, such as Chinese characters. I am working on the problem and will fix it as soon as possible. I am very sorry for the inconvenience.
If you like, you may use another user on your PC to play the game and later manually copy saves from that user to your normal user after a patch is released.
