Same here; Diamond IV ~100 points or so away from D3, downloaded the Lost Treasures update Tuesday and then logged on and my rank is Gold III, though the rank right above my Legend avatar was still Diamond IV (similar to how it looks after a Rank Season Split). Was a little confused so I queued up, played a game and yup, my official rank was reset to Gold III after finishing that match and the rank displayed over the Game Mode options and over my Legend avatar then both said Gold III even though the Rank Season Split isn't scheduled for another 5 days. My biggest concern is that I'm wondering if in 5 days, our ranks will be split again between our incorrect newly given ranks (in my case, Gold III) thus placing us even LOWER after the official split, as if our ranks were split twice, or did we just receive our Rank Season Splits early and will be unaffected by the official one in 5 days? In which case we can just begin climbing 5 days earlier than everyone else which may not be that bad considering we receive no rewards until the end of the season anyway. The ladder seems like the only acceptable outcome because if they somehow do fix this before the official Rank Season Split and return us to our previous correct rankings, we will have lost 5 days to increase our rank before said split. Not THAT big of a deal but hey, I could probably climb from D4 to D2 in that amount of time so, still... that would be kinda butt.
