Emotes not working

I've been playing for the past week or so and my emote wheel is blank roughly 70-80% of the time. At first I thought it was just me, or maybe it could have been because I had just gotten back into the game after a few months. But resetting my emotes did absolutely nothing to fix this. Then I looked up "emotes" here on the boards and sure enough, the reporting a bug section was full of people with the same problem. Why has nothing been done about this? I know it doesn't affect overall game play very much, but I do miss flashing emotes to have fun with my teammates and the enemy team. Furthermore, people PAID for these silly things, and this has apparently been going on for a while. Can Riot please do something?
