If you are downloading only the official version it will retain your saves every time you update, to any version.
Updated the game like you said and Thank you! But after loading my last saved file it still says i finished the ver. of the game even the other save files that are at 34% it still says i finished the ver. of the game and the map has reset, some areas are missing too. Hoping reply. :))
Edit: No matter what save file I load it always loads at 26%
