I have an Idea and its gonna be very useful If you go to your profile your gonna see a Permanent Save If you click on it everything you have will be saved even if you Uninstall the game and Reinstall you can go back to your account and Press Load then you will have everything that you had! this will be very useful for players losing progress!
Also btw if you unlocked Null and you saved your account and uninstall The Game And re install it and load your account you have to Re Unlock Null Again which is useful
