* F1 now toggles

New Bugs:
* Game may crash upon entering the Nether. When you reload you will be at spawn with no items.
* Some users reporting worlds getting deleted (confirm?). Deletion may be caused by use of mods from 1.2 that have not updated.
* Levers can be placed on the bottom of a block, as long as there is an open space, and a block horizontal to the open space. The lever will act as if placed on the horizontal block, but looks glitched, as shown here: Media:Brokenlever.png
* If someone uses their bed in SMP, other players may get disconnected. (Un-Recognisable Packet ID: 17)
* Wooden Slabs are best mined with pickaxe, not an axe.
* Zombies cannot hurt players unless they are above them.
* If you toggle F3 (Debug Interface), and leave your world/server, the FPS tracker will stay with you in the main menus.
* Large chests may cause crashes when opening them (Unconfirmed: crashes may be caused by use of mods from 1.2 that have not updated).
* You cannot place two different half-size blocks one above another (space is created between them)
