Hello. My english is not the best, but I can understand you... Well, the problem I saw is: In creative mode, I can fly to the sky (up) forever... without stop. That's... weird.
Whenever I try to open the video settings, the game crashes. This happenes in: The main menu, SSP, SMP
No Light Glitch
When facing certain directions in creative, The character looks completely dark as if he is in an unlit cave.
Creative mode Arrows Bug
When you give your self an arrow from the creative menu and then shoot the bow you lose the arrow and need to get another.
Iron Bars, Fences.
Iron Bars, Fences, and some other items can now be placed on top of tall grass. This shouldn't happen.
