Description

I was wondering if it would be possible to get the mod to work on singleplayer mode/LAN servers created from singleplayer worlds. I tried putting the config file in the config folder for the Minecraft instance but it seems that the mod doesn't work with that as of now. Support for singleplayer/LAN would be greatly appreciated. Thanks!

This feature probably needs a rewrite. I will keep this issue open first until a further decision is made.
