Server crash on startup using Mohist hybrid server.

Unsure if making the mod compatible with hybrid servers is a priority given the nature of the mod, but wanted to send this crash log this way.

The modpack I'm running works just fine with it in singleplayer, 100% something related to the Bukkit API from what I can see.
