Ultimate Endgame

Alright, this one fixes a lot of major bugs, and adds one new thing.

-Fixed the Dark Nether, now it actually looks like a darker, shadier version of the Nether

-Fixed the texture for Bulminite Ore, the one I used in the last version was wrong

-Fixed the Bulminite Ore drop issue

-Added Dark Nether Quartz. I plan to add more functionality in the future, but right now right-clicking it in the air should give you a short buff

That's all for now. I wanted to fix some stuff, so I wanted to get this version out as soon as possible.
