Horrible Upgrade Experience

I have invested a significant amount of hours in this game. Upon upgrading to the Doppelgänger Pack the game no longer works. The message you get is “Borderlands the Pre-Sequel is damaged and can’t be opened. It instructs me to delete the game and download it again from the app store. It is amazing to me that these guys have not fixed this problem since this also happened to the Borderlands 2 game. So all of the hours that I have invested are gone. Warning do not upgrade or you will loose your caracters and have to start over again. There is a fix for this all you have to do is backup the save data folder and copy it to the new installed game.
