Okay so I disconnected during a game. My opponent played a card, and my screen was left the same for a while, without the card animation ever being shown. So I decide to reboot hearthstone. My game continues, but I lost a turn. I realize that my opponent had the name "UNKNOWN" and no rank, even though it was a ranked game. After the game I decided to go on my friends list to see if i can get his username, but it wasn't on there.
