I thought fof all the things to lose crowns, there is buying clothes with crowns, money with crowns, cards with crowns, and those ches tthings with crowns. Buying clothes couldn't get my to 5 crowns, money for sure, and cards was just impossible. Due to no membership, I can't test out the chest idea, but my friend told me it was possible. So I mark this "Case" to be Closed.
