I'm not sure this is the appropriate place to ask this question, sorry in advance if it's not. For the last 40 or so veins I mined I got no rough/coarse stone. The copper/tin ores still drop. Now I may be incredibly unlucky, but this looks like a bug to me. This happened for two characters. For the first tens of veins I mined rough stones would drop, but then at some point they just stop dropping. I tried reinstalling (or, well redownloading) the game, I have no mods installed. I asked around and no one else seems to have this issue, any ideas?
