Rolled back in ranked in the middle of the month

My rank in the rating just decreased in the middle of the month I reached the rank of gold 3 (not much … =)) now when I enter the game my rank is in the standard gold 6 and the chest with rewards for gold 3 …
I hope you fix it before the end of the month I would like to play some)

you havent played in both standard and ranked by any chance?

I discard all the old cards and did not play wild for more than a year.

Gold 3 was the highest for the season. You can still lose matches and drop down to Gold 6.

No,in new ranked system at gold 5 u have non promotional rank floor.You can’t fall over 5 gold))

you are gold 4, not 6. IV = 4, VI = 6

and you can drop from 3 to 4 when losing games
