DO NOT finish the last box in the quest if you are not going to have the 8 you need for that week. Save the last load for the next week and then you can get 8 for the next week. Do not finish all your quest unless you know you're going to get 8 in that 7 days. If you will have 3 quest for the 7 days, save the last box in other quest for the next week to add up to 8.
