client exits me from draft queue.

idk how it happens because im always tabbed out the client when it does but it goes like this, i start the queue to get into the game and the timer starts counting how long it takes, as usual but then i close the window to look at youtube or do whatever while i wait. I noticed ive been waiting longer than usual and open the window back up to see im no longer in the queue timer yet the little clock that tells you how long you've been waiting is still ticking and says 8 minutes
