Hi,

I downloaded your plugin and it's throwing errors. Any ideas? Thanks in advance.

Thank you for the report; I'll look into it

Your Spigot is outdated. Tell me if the issue persists after you update Spigot to the latest build.

The plugin uses the interface added to Bukkit on August 10, and your build seems to be built on August 6.
