Bukkit

Version 0.0.1 (Initial release)

Throws a "severe" message in the log sometimes when blocks are broken by the player:

Could not pass event PlayerInteractEvent to ArenaControl v0.0.1

This is harmless, but will be cleaned up in the next version. It's caused when this plugin tries to look at the (now broken) block to determine whether the player is right-clicking a sign.
