today I wanted to play a rated game with the standard matchmaking system. Because it couldn't find an opponent within the level range I used, I toggled it down to also include lower rated opponents. While I was holding the button to do that, the client connected me to two different games at the same time.
I noticed this, because I had a small issue with my WLAN connection and reconnected and then was reconnected to a different game with a different opponent.
The game numbers (taken from DomBot on the Discord channel) are 77491387 and 77491388.
