So I was browsing my youtube one day, and I came across a mod called "MineUp", in this mod, the over-world, sky-world, and nether are all in one dimension, and I found the mod and its outdated. no one seems to want to revive this mod, or it has been revived and I just haven't found it.
Point is, I really want someone to make this mod for 1.2.5 =3
