- Running CB 1.1 R3
- Running latest version of Spout on the server
- Disabled NoCheat (in case of blockbreak.noswing.check problems or otherwise) but the error still occurs

The plugin works as intended: Right-clicking while holding dye will dye the wool properly (tested with every color). Right clicking on wool without carrying dye does nothing to the wool, it simply spams the server console with error messages. The plugin and server will continue to work without fault after this, but the console spam is too annoying to deal with.
