Game History Bug

Been seeing this problem creep and grow since the last patch. If you click on a game in your game history, you can bring up your scorecard. and runes. But the graphs and stats screens have been hit and miss - either blank or it comes up. The overview is just a blank screen. (Ironically the game overview on the web is similarly blank.) Haven't seen anything indicating that it is being worked on. But what is up, Riot?
