One ore from one miner with credo lit by one torch, but still the two parts melt differently, which prevents the ore from smelt with 9 coal. Сan i find out if the problem is the stones chipping off the boulder?
Yeah, I noticed that too. Wasn't a huge fan of mining out a section of wall for a ore I was after, and in turn getting a bolder that gives me no bonuses (except maybe a few extra quantity? But what is quantity worth vs quality race in this game)
