it replays the last ranked match update animation, but does not actually change the rank.
That is, my last ranked match was from plat 1 with 3 bars down to 2 bars.
And the same animation is shown after every non-ranked match (again from 3 bars down to 2).

I lost progress towards my rank twice after playing and winning in unranked matches.

Lost in Ranked to drop from Gold 4 to Gold 3. Played fun decks in standard Play queue (non-ranked), and even wins de-ranked me, now down to Gold 2. This patch is definitely broken.

yup this has been happening to me a lot since the new patch

After the update on September 17, 2020. I lost two ranked points when playing normal games. Lost one game and won the other. Getting to the rank I am has been difficult so losing them like that is not okay.

Okay, so I figured out what's going on. If you play a ranked match then a regular match, the animation from your last ranked game will show again after the first regular game. It doesn't actually change the ranking, just replays the animation from last time, and it only happens after the first unranked game. Something that still needs to be fixed but not catastrophic.

Looks to be bugged. I got the same thing.

<< Translated by Google Translate >>

Even when I win ranked matches, I lose rank. I noticed this now, but I believe it happened several times.

How to proceed?

Mesmo quando ganho partidas rankeadas, perco rank. Eu reparei isso agora, mas acredito ter ocorrido várias vezes.

Com proceder?

While playing Zendikar Sealed, my limited rank decreases after winning a game. Attached log.

Please merge thread if necessary. I've been losing rank even while winning matches in limited formats. The game will count my wins for rewards purposes, but not for rank.

I lost rank in a non ranked match

I was testing a historic deck in the non- ranked area. i won the match as well for insult to injury. im rank 4 platinum.

Same issue. Opponent conceded the game in Zendikar Sealed, my rank went down by one instead of up by two.

It happens for me when I play in a standard match, and then switch to regular play afterwords. If I close out and go straight to play it doesn't affect my constructed rating.

Same here

Possible clue: I just saw my Constructed ranking go down by one bar, but I'm pretty sure I had NO bars in my ranking before my win. Might be just a graphical glitch?

Same thing happened here. Im just trying to get my dimir deck working :(

for a strange reason im playing unranked and losing ranks after a win.
