Ranked Queue Bug

Seldomly, but frequently enough, in ranked solo/duo queue (haven't tried this in flex yet) after you pick a champion the entire screen will go blank. Sometimes it slowly comes back, but most of the time it results in a full client crash. Thankfully this hasn't happened during a series so no free loss, but you should really look into this to prevent people who could be in that situation where their client freezes due to this bug and now they lost their series.
