Don't worry it's normal it's just because on RenPy I didn't change update number so by default it says 1.0 but if you download the 0.8 files from MEGA then it's the last update.
it didnt work when i loaded the las save it game the thing with the next update ......
The only new thing in this update is Prin adn Sarah's epilogues so if you go to any other chapter it will not add anything.
