i want them to have access to a disposal world, but i dont want them to be able to get to the nether or the end, unless they have been there before,
so once they can get to the nether, THEN they can use the nether warp.. warp Ndisposal
and the end, once they get to the end, they can use the warp Edisposal .. but not until they have the achievment for it.

any thought guys.
essentials is what we have for warping around
