so im having some trouble figuring out what im missing for total mastery rank. i saw someone link to framedex.net today which is a site used for tracking everything mr related to help you see what you need to do and how much you need to get to the next rank up. i have leveled everything excluding beta and founder items as well as a few archwing weapons and one amp. im missing a total of 6 items not including the beta and founder items and it say i should have a total of 1,554,669 xp when in game i only have 1,539,113 for a difference of 15,556. what could i be missing im sitting at 432/438 items and all missions and junctions are done. anyone have any idea what that 15,556 mr could be?
