Everything goes smoothly except for the occasional lag spike, then around the 10-15 min mark the game screen freezes, goes black, and closes, and I go back to the "game disconnected, would you like to reconnect" screen. If i click on that nothing happens and i get stuck loading it. I have to completely close LoL relogin, then rejoin the game, after that crash gameplay is normal except for the icons of items being randomized. The thing is this seems to happen only once per game, including practice games.
