Potterygrr246: I've experienced this problem a few times myself! If you log out of origin and then log back in, it should help resolve it. I'll add you to my friends list now though :)

August: they randomly appear when you tap on buildings in your friend's towns. I think it's a 1-2% chance they'll appear, so the more friends you have, the more tapping you can do, and the higher the chance you'll get them! They also randomly appear when you get Homer/Lisa to clean up debris in Springfield.
