Leveling Experience stalled

Today I was playing a bunch of games and I don't seem to be gaining any experience, literally the experience is stuck? If it's false let me know but I played so many games today and it hasn't gone up at all, also the experience rate dropped by a lot, I used to be able to get about 400-700 by playing a full 13 round S&D game and now I get about 100-200, what is going on? I hope this can get fixed.
