EssentialsNK 1.9.3

Useful plugin, but when I write /back it teleport me in a hole and fast I died, please repair it.

This is great, thanks! I am able to use per-warp permissions by giving nodes like essentialsnk.warp.island to perm groups. Something peculiar about the setwarp process is that warps often revert and go to the coordinates in the same world, not remembering correct world to warp to.
