Ok, I reinstalled the app and none of my data was lost. Thats good. Now for the cash, gold and keys stuck on zero issue. The game keeps a record of whats spent and whats earned in a .nsb file. So obviously you re going to spend a hell of a lot more than you earn using this mod. Which puts you in a huge deficit .
There was a way to rewrite the .nsb file, change your earned/spent stats then save it back into the game. But, CSR2 has removed the recoverpp file which was a very crucial step to accomplishing this. (Also couldn't do this with a mac. Needed windows. Bummer). So if this mod doesn't get updated I'm afraid that your game will be stuck in a deficit until someone figures out how to save a modded .nsb file without the recoverpp. I have found zilch on this yet.
