Null?

Just today, i found out that all usernames in the game (Featured Levels and Browser Levels) were read as "null".I found out that it was just some bug or something that Jim was doing, and i also had trouble logging back into my TJF account because of it. Jim will fix hopefully. The picture on the right shows (in my level browser) a picture of the bug. I'm just letting you all know about some strange thing happening, well at first i thought it was a glitch, but it's just some messed up bug. I don''t know how this happened.
