Game Crashes at 100%

This bug has made me lose two ranked games already. I look on the forums and it seems this bug has been around for three years. It needs to be fixed because if it doesn't your client becomes an even bigger meme. The forum post i looked at had 60+ up votes and no rioter has replied. This needs to be fixed to keep riots integrity for if it is ignored they look like they don't care about their client.
