[GAMEPLAY] Can't remake

Had a game where one of our players never connected, but we couldn't remake. If we tried /remake it would say one or more players needed to be disconnected, implying that the player was connected. Yet about 5 minutes later the game gives the notification "A player has reconnected", implying that he was not connected. Not sure what other info I can provide, but here's the match http://matchhistory.na.leagueoflegends.com/en/#match-details/NA1/2478612350/206784146?tab=overview
