This is also happening in the main server. I've been eating melon slices, and for some reason, whenever I would get that message, the melons would just not effect my hunger bar at all. I would eat and eat and eat and nothing would happen. Eventually, it would "fix" itself and I could eat the melon, but... It's really disconcerting to see the AntiCheat warnings popping up.

So... help.mojang,com is kind of broken. It's always fun when your service status detectors can't detect your service status. They really broke something.
