[CLIENT] Champion Select Bug

Someone help! When I play ranked draft or normal ranked queue, my client will sometimes just bug out and I will not be able to see anything like the next champion picks and/or I will not be able to pick my own champion, summoner spells, runes, or masteries. I have no idea when this started, but I know that the problem is just becoming more frequent. This has caused me problems, because it counts as a dodge when I had no control to do anything, but wait. I will still lose LP if it's ranked and I have to wait the standard amount of minutes before I queue up again. Any help would be greatly appreciated. Thanks again~
