just tried to play a ranked game, which i rarely do, and got to where the loading screen is supposed to pop up, and it was just black. i have NEVER left a game on purpose. Now i got a leaverbuster warning, and its the only warning ive ever gotten in 4 years and 1000+ games. really disappointing. i tried relogging and restarting pc. tried all the solutions in the help page. Never got in to the game. just tried custom game, doesnt work.
