The new ranking system operates in such a manner that when the percentage bar indicating your rank’s progress fills up, instead of promoting you to the next rank, it resets the entire percentage bar back to the starting point. This issue has been noted by several users on the forums, indicating it’s not an isolated occurrence; it has also made its way to one of ‘Necros’ videos on YouTube.
I will link this video for you and for the devs to hopefully understand:
I am experiencing this when i get to “0%” progress and the the end game screen fails to demote me or show my progress in the demoted rank. Instead of demoting me, it still displays bronze 1 with 0% progress. So if i win the next game, I am getting re-promoted and the end screen incorrectly showing me getting promoted to silver 5 when in reality am i only getting re-promoted to bronze 1. Your rank is probably correct on the back end but the displays are jacked up.
