I know there is no bug happening for you to fix, but this would essentially lock someone out of their world if they happened to log out near one. I am playing single-player so I understand if there is no fix for this, but I would like to inform you of this. The only fix for this on single-player would be to disable the mod and load the world, re-enable the mod and load into it again to regain your world. Hopefully you or your team(if you have one) will be able to implement a fix! Though, again, I would understand if this mod is more for servers and there is no fix for single-player.

This mod should definitely work in single player mode. Are you getting a crash? Could you post your latest.log and crash report?
