My Killer rank was reset to Qualifier, any reason why?

After the last update my rank in ranked leagues went from Killer to Qualifier. I have to work my way through gold tier again, not all that troublesome but this might be a problem other people have experienced too. Have other people experienced this?

It looks like a good amount of people have reported this in the bug thread, so it’s not just you

I was reset too, but I didn’t keep on playing. I left the game because I saw the other stats were fine. Then when I started the game again I was killer. It was a relief…It has happen something similar in other game I play, so I just didn’t “overwrite” the rank by playing a match, just in case.
