2 AFK

So I just got on to play a game right after the server got back up. Right before we were gonna win, we got 2 afks that left at the exact same second. I assume this is from server issues and there were no signs of them being salty or needing/wanting to leave. We ended up losing to 3v5 (obviously), and then got trash talked by a couple of egotistic jerks who thought they were everything for winning a 3v5. At the ending screen, there wasn't even any loss prevented. What happened?
