Currently, the crazy enchantment support is broken because CrazyEnchantments is currently being changed and these changes broke the API. Unfortunately, the old maven repository is gone and the new one is not yet published, so building this plug-in is also annoying in the meantime...

This has been fixed in Custom Items 11.3 (although the work-around is rather dirty). I will wait until their maven repository is up before I can fix it properly and close this issue.

This was fixed in KCI 12 (at least for now)
