Cocoa beans

• Can now be placed when aiming at blocks that it cannot be placed on if there is an adjacent block that they can be placed on.
• Can now replace replaceable blocks such as snow, fire or grass when placed by the player.

Infested blocks

• Now break instantly, regardless of a tool that the player is using.

Levers

• Flicking it on now displays redstone particles.
• Can no longer be placed on top of pistons.
