Does anyone have any tips on how they play the milestone challenges? I feel like I can never earn enough items and make it to the end before time runs out. There's less than four days left of the Pumpkin Party challenge and I haven't even earned enough golden gourds for community prizes yet. I have six farms, four nests and two evolution flowers but it still doesn't seem to be enough. How can I earn more items in time without spending my gems?
