"Because we store your progress in a given week, you don't need to clear the activity in one-go. Your group could simply make your way into the Vault and call it an evening, reconvene later in the week and pick up where you left off." "However, your progress for the week is reset each Tuesday at the Weekly Reset." Nice quote from a Bungie Worker under the name of Luke. Good to know that we won't need to finish it in one sweep.
