I'm not sure if this is a bug, or just an oddity in the way the game detects disconnection.

Our did not move from the fountain for the first 7 minutes of the game. When he returned, he said that he had had to restart his client, then restart his computer (he wasn't just afk). The game never marked him as disconnected, so we were unable to remake the match.

Interestingly, the player's item build order is blank on the match history page, however I was able to find the build order from lolstarz.com: https://s28.postimg.org/knidsx4f1/league2.png

This should show that the player did nothing until past 7 minutes. My suggestion is that perhaps disconnection should be based on inactivity (sitting in the fountain) as opposed to whatever else happened here.

I also realize that a lot of people are having problems with disconnects when loading into games, but even so I think a remake should be allowed if it takes 7 whole minutes for them to reconnect. The match is heavily unfair at that point.
