Well, for the past 3 games, I have gotten an OOS, from 3 different people. I just watched a replay of Waseem Vs Hash, and it came up with those two names on the OOS. Im wondering how to stop this.

Try refreshing your page. It may be because you entered a match while watching a replay.

if you don't wanna reload the page you can simply click on any live replay and quit watching it before you enter a match
