I have a clearing quarry card going in the nether, and for some reason, it is mining dirt... I'm really confused as to why this is since dirt doesn't spawn in the nether. I am in Minecraft 1.10.2, playing in the Modpack AllTheMods. I also have a builder running a normal quarry in the overworld, but it voids dirt.

Are you sure somebody else didn't already use the quarry there which replaces with dirt? Or maybe a pump?

Self-fixing mod :-)

If a modpack doesn't include RFTools I won't play it! Simple as that :P

I am the only person on the world, it's working now. I don't really know how to explain what just happened. It's working normally now so i guess the problem is fixed? lol

BTW, I love your work. RFTools is amazing. Never had a problem before now and it seems to have fixed itself!
