I want to transfer my save from one PC version to another PC version, is the save a Text file on PC, and if so what is the extension of the file, and where would it normally be located at on a Windows computer? also would it be a horrible idea to transfer a save from an old version to a new version when the version is only one update in difference?
All old save files are fully compatible with the newer versions of the game, and will automatically be updated on loading. The upload/download file menus (accessible in the save/load menu while in game) currently aren't implemented on PC, but those menu's will tell you the folder in which the save files are stored. Just copy the saves over and they will work. The extension is .gsv
