I play lots of group goals. I think they are a great addition to the game. My problem is that I often don't get credit for doing the tasks required to complete the goals. I use up all my groceries and then I notice. Flustered, I turn the game off and sometimes return to find the goal expired. I know I should always check to see the banner is on the bottom of the world map, but when the goal automatically bypasses that screen, I sometimes forget to check. There are even times the goal is on the world map and I still don't get credit (this sometimes happens when collecting rare objects). It is very aggravating to do the work, but not get credit and run out of supplies.
