Debug mode stuff
There are literally thousands of things you can do to break the game with debug mode. This is because the game is only designed to work properly when playing normally. Debug mode is just a developer's tool that was left in for fun. It's not part of the game and anything you do in debug mode doesn't count as a bug. - Hivebrain 04:50, 9 April 2008 (UTC)
