Gameplay
Bugs ! Hopper duplicates certain items. When thrown on top, items are duplicated and deposited into chest. Tested with hopper placed beside chest, single player, Mac. Duplicated water bucket, hopper, fire resist potion. Did not duplicate beef, seems random. Does not duplicate same items when placed inside the hopper.

! Whenever i enter a Minecraft world that is not superflat, i spawn underground inside stone, not in a cave or anything related. I then start suffocating. I am using a Mac in singleplayer. Annoyances undefined Daylight sensors are always active in the Nether.This is on a Mac in singleplayer, although it has not been tested in multiplayer or on other operating systems.
