Bukkit

Have you updated? You should update WorldEdit to the latest version.

Note: CommandBook is designed to be backwards-compatible with old versions of Bukkit and Minecraft, and also forwards-compatible with newer versions of Bukkit (within reason). In order to update lists of item/etc. names, however, you have to update WorldEdit.

Changes in this version:

• Fixed missing support for enchantments in kits.
• Added storm and sun commands as aliases.
• Added node commandbook.locations.target for #target. (eg /tp #target, /put)

• Maintain pitch/yaw information for non-player teleports.
• Fixed the return command.
• Fixed warps/homes remove command checking wrong permission.
• Overrided vanilla 'w' alias for tell command.
• Condense and corrected /gamemode permissions checks.
• Use decimals instead of whole numbers for teleport commands.
• Refixed stack issue.
• Fixed teleport command from commandblocks/console.
• Added auto enable config setting to flight component.
• Added a component to control flight and walking speed, as well as flight permission.
• Added gamemode command vanilla support.
• Re-enable IP bans * use the ipban command.
• Don't teleport players in vehicles. Eject them first.
• Updated sessions to only create files when a player actually has a session to persist.
