The vanilla diamond pickaxe still has a considerable durability, especially if it’s enchanted for Fortune III & Unbreaking V (not sure if this exist in 1.7.10) and used only to mine appropriate ores. And moreover, there a diamonds in easy access and it’s guaranteed to drop a crystal. Isn’t it wrong?
I checked gregtech.cfg and found this:
general {
B:DisableVanillaOres=true
}
So this option doesn’t work?
So I found this mod, CoFH core, and I checked your config pack: there is a config for it, and there is Vanilla.json with empty brackets in it—I guess this one just removes vanilla ores. Should I install it?
