I bought enough mystery boxes to buy the two shops which I never would have done if I could earn hearts. I know I should have more self control but since this game is designed for impulse purchasers of donuts it makes me wonder. If only people with large cpmplex donut purchasing springfields are unaccessable to friends right now it's a slap in the face. I've also noticed that the more complex my springfield gets the worse the connection problems are.
