1) All of the commands under Useful Commands in /help 6 are bugged. If I type /points, or /intro, nothing happens. But if I type /swearing, it'll say "usage for this command is /swearing." Both /refer code and /refer help also send the same message, saying "Use /refer code, or /refer help. If you were referred by someone, type /refer <Their code>.
2) This one is already known, but not fixed so I'll be stating it anyways. The name of normal users doesn't appear, all you see is the rank, and the message.
3) I found an area where when you pass the tripwire hook, the dispenser will give you a cookie. Well, with that cookie, you can eat it and start getting some crazy regen, but that is temporary because after you ate the cookie, your hunger doesn't stay fixated at the same amount, it now decreases like normal. And the amount of hunger that you have when you die, remains the same until you relog.
That's all I can think of at the moment. If I find any more I'll be sure to notify all of you.
