I don't understand how to get the quests to be collected all in one week. I do eight and some expire before the end of the week, so I end up with 5. So when I turn them in two are wasted because I only need 3. Two vanish because when I turned in my three all five are taken. After doing 8 quests I end up with ONE FC. What's the secret way to not get them to be wasted? Most of them expire or vanish before I can collect my FC and I end up doing a lot more than I should have to.
