Peculiar data points in the add-on mission census data...

The census data includes information on players who are, for example, on the Zilart mission "Awakening," i.e. the number of people who have completed Rise of the Zilart. Same thing with Aht Urhgan mission "Eternal Mercenary."

But I look at the data for A Crystalline Prophecy, and I see no information on who's on mission "A Crystalline Prophecy (fin.)" Even more interestingly, they do include people on "A Crystalline Prophecy," which is where you are if you haven't even purchased the add-on, or at the very least have yet to enter Lower Jeuno to trigger the next mission, "The Echo Awakens."

The other two add-ons are in a similar situation: apparently showing info for people who probably haven't even bought the add-on, but no info on who's completed it. Instead, all it seems to show is the number of people who got up to the final battle only to be frustrated by and/or gave up on it.
