The Style Guide has recently been rewritten. Please take a moment to review the new guidelines.
Other bugs I've found so far:
1) The Teleport Maze no longer displays anything but a moving background, making it almost impossible to navigate.
2) Some areas have had their boundaries broken, so you can walk through some walls and objects (for example, in Sign World, you can walk through the small signs with faces).
Man, they really dropped the ball with this version.
