same ****ing thing just happened to me, but it's the first time, I can't reconnect ... I can just get another leave due to S2 bugs. It will be my second in more than 1000 games...
Well here goes how it happened, we were winning it while I was playing empath and my team was pushing, and out of the blue when I was about to gank another guy I got disconnected and I've been trying to leave the game, check the old games etc, the game can't be found. And I can't reconnect. So, Leave #2 Thx S2 Games.
