Overall I love the app but with the most recent update I'm experiencing an issue where it appears trees cost more coins than they display. For instance, I cannot purchase a 600 coin tree with 673 coins because I don't have enough coins. Also last night I had 1272 coins and bought a 600 coin tree, bringing my balance down to 501. If this could be fixed, I'd love to go to 5 stars. I literally use this app all the time.
