I have been wanting to make limestone, it's needed to make mortar and I need mortar for fireclay bricks to make bloomeries and such (also just want to make normal bricks). I searched a massive radius around my base, I'm talking about a full day, day and a half distance (as the crow flies) just trying to find some lime stone or chalk pieces. No luck.
Finally, I relent, I download the xray mod, I figure while it is a wee bit cheaty, I still have to make the journey myself.
There's none. No chalk. No limestone. Not even marble. I tried a 30000 block radius. It still cant find any. I tested it on other metals, it certainly can find the tin. But nothing related to chalk or limestone, be it boulders, stones, or blocks. What is this?
I assume xray only scans what your map can see but even then, it's kinda taking the piss considering how common limestone is as a rock in he world.
