Bukkit

v2.2:

• Supports a much wider variety of stones for the portcullis top. Now supports just about any type of stone-like material for portcullis, including some of the craftable varieties like chiseled stone, etc. Same recipe, just more things can go in the center piece.
• Fixed some miscellaneous bugs, such as if you destroyed a portcullis by having another portcullis lower its gate through it, the portcullises would get into a bad state and typically throw some exceptions.
