Description:

An issue where The Dreadlands fail(To clarify, when I say 'fail to generate,' I mean that there are no such biomes as Dreadland Mountains, Dreadland Forest, and Purified Dreadland in The Dreadlands. Instead, everywhere I go in The Dreadlands, I only encounter the standard Dreadlands biome.) to generate these biomes: Dreadland Mountains, Dreadland Forest, and Purified Dreadland?

Latest log file for when the issue was present:

Hm.... that's a new one. After looking through the code of some of the mods, Better Mineshafts is the only one I could think of that could mess with the dimension, but that "messing" would be replacing the mineshaft generation, which shouldn't result in the whole dimension seemingly switch to only generating a single biome.

Just to ask the stupid question, you have made a new world and flied around checking to ensure that none of the other biomes generate, and didn't just have really bad luck?

Since I can't really find an obvious culprit, best advice would be to try removing mods, and by doing so continually narrow it down until biome generation in the dimension works.
