It looks like your TC might not be configured correctly in your bukkit.yml ...

Please make sure you follow the wiki instructions for configuring your worlds.

If you do have your TC configured correctly I will either need some more information regarding your worlds or I will have to make a couple debug jars for you to run and let me know what the output it :D

Inactive. If you can provide the information Timethor asked, the report can be opened again.
