I found a lot of issues in the last release, so it is highly recommended that you update to this version (1.2.5)

• Fixed plugin not registering syntaxes correctly (from 1.2.2)
  
  
• Fixed very rare server freeze possibility (noticed after using it in 4 servers over a week)

Sorry for the inconvenience, but this is my first public Java plugin, and I keep accidentally leaving some things not working correctly while trying to improve the plugin
