I'm playing All of Fabric 3, want to mine Lead ore with the miner, searching now for an hour but didn't find the vein called "Galena". Roughly Enough Items tells me that it's the only vein I can mine lead. Could it be that it isn't generated cause Lead is distributed by another addon and is disabled by config in AOF3 by defualt?

Ok after more searching ingame I found out that its in desert biomes :D
