from person to person the bank balance should have changed to be different, yes? Mine will pick a number and each person's bank balance will stay on that number. Happens when I close out of the game at the beginning and go back into it at the adoption screen. For example: the game works well until I have to close out completely and go back in, each person's bank will be 100. Normally, a person will have 300, 150, 350 or so on when you choose try again.
Clearing cache and storage will fix the issue temporarily, but the app will continue this if I happen to close the game during adoption.
