Been having an issue with not getting the alerts for new posts a bit more than usual. I've heard a few people mention it was happening to them as well.

Not sure if there is anything you guys can do, and it's not a huge problem if I go into each game and look, but if there is something you can do, you won't know to try unless someone tells you, so... ta da!
