Hey Vaz, can you add your limestone, marble, and basalt to the oredict so that they're compatible with Chisel, and vice versa? Chisel-Team/Chisel#463

I tested this by simply leaving the configs of both mods at default and starting a new world. So both mods added their default limestone, basalt, and marble to the world. I then tried crafting your (limestone/basalt/marble) stairs using chisel's blocks. Nothing. And alternately, I tried using your (limestone/basalt/marble) blocks with a chisel. Nothing. I then tried using the mod "Ore Dictionary Converter" (which allows you to convert a block into it's ore dictionary equivalent block), and nothing showed up in the conversion menu (no conversion equivalents for any of the three blocks). At that point, I assumed that one mod or the other wasn't ore dicted, but they might just be ore dicted differently. Long story short, they don't recognize each other.

All of the quark stones have been on the ore dictionary for a long time now.

The blocks shared by the two mods are not compatible, that is the real issue.

They should be working fine if they're both in the oredict. Which version is this?

Hmmm... when I posted this I was using Chisel - MC1.11.2-0.0.11.16, and Quark 1.11.2 r1.2-93. I wonder, are they using different ore dict prefixes maybe? Like maybe one mod registers them as "ore_block" while the other registers them as "ore_stone"? I can ask the Chisel team how they registered their blocks and report back if it'll save you some time and effort.
