[CLIENT] Black screen in Champion Select after I waited 20 minutes. Its very annoying, please fix.

In addition to Rito's horrendous leaverbuster system, the client comes with bugs which make you wait the leaverbuster time, but not be able to select a champion.

I was waiting my 5th leaverbuster with my friends, and the 20 minutes finally ended. When we got into champion select, my screen went black, and I was unable to select a champion, due to this, they left the queue and said they'd play on their own. This had me very stressed out.

I'm sure other players have had this bug occur, and it would also help if you could work on your leaverbuster system. It has many players stressed out over this and has wasted a lot of their lives that they won't ever get back.
