First of all it's best to keep a backup of your families in case it gets close to ending such as times like this. Although your peeps are 56 & 57, some will actually still have children around that age!

I recommend you backup your game files immediately before you do anything else, you can see how to do that here.

If your peeps do not have children, you'll likely have to wait for the adoption which means the backup is crucial. If your family does end, you can always use your backup and try again.

Best of luck!
