just a technical question: how do new versions (like 0.21) find the old 0.14 save games? I usually just extract the new version right next to the old version, but in a differnt folder with the version number in it (I just leave it like the zip file I download). So I do not copy any saves, but when I open the new version I can still select all saves from the old version. How is that magic done? And: will they disappear when I delete the "old" folder?
