This game will forever be marred by hackers. Unfortunately you lose 30+ minutes EVERY TIME if you make it to late game and come across someone doing this. These hacks have been around for over a year. This particular hacker
had over 100 matches on record (and presumably he also ruined for hundreds of other players) at the time I caught him. So a lot of these guys aren’t getting banned quickly, and have the opportunity to ruin thousands of player’s games.
