i think there should be a counter for these events where you are required to go to a certain amount of casinos to get an item. The counter could start at the amount required and count down every time you visit a new casino so that there is no guess work when as to when you will be finished for the day. I think this would encourage some people to continue participating more readily in global goals because it would allow one to have a visible record of how many they have left to finish the task.
