Forum Thread: Wasted Missions at Frontierville

I wonder if something is wrong with these 2 missions: Apple Pie Contest and Help Neighbor Make Cheese.  As I go visiting from one neighbor to another, a green check mark would confirm that I have finished the mission. But, unfortunately, when I go back to my homestead, it's still untouched. It's as if I have never done anything at all! Where have all my efforts gone? Is Zynga's apps. defective?
