As the title says, Gany's Surface also adds andesite, but the recipe for polished andesite is four andesite in a cube, same as your andesite brick recipe. As such we can't make andesite brick.

I also brought the issue up with Gany, so maybe you two can figure something out?

Thanks for all the hard work, Vazkii! Stay amazing.

Update: This issue also affects Basalt and Granite. Basically the 1.8 stones.
