This mod always seems nice on the surface, but it's too much. All the biomes are basically cosmetic and many don't play well with other mods. Some problems are cactus, rubber tree, towns/npcs, , thaumcraft trees, other types of biome-specific items, and other items that mods spawn on the surface of only vanilla biomes. I made a world and flew in one direction for 30 minutes and there wasn't a single village, rubber tree, cactus. I don't think i'll ever use this mod. Try skipping step 2, it shouldn't be needed with step 4.
