dont complain about bugs, notch didnt release it officially for a reason, its not finished, but since someone betrayed mojang and leaked the update before all the stuff was fixed, well thats why it has the bugs. personally i rather wait for the official update, when its finished, i feel like judging a leaked unfinished version of a game is like publishing a book before its been edited and fixed up, or taking and showing a painting before the artist is finished.
