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.

Hi Kammi. In order to see the results you want, you'll need to complete the adoption process before you leave the adoption screen. See my response as to why here.

Of course it's different if you're choosing one of the children to start a new generation. All of the children will show the same amount of coins in the bank, as it's their inheritance.
