Yeah I saw the people mention the bug, but they failed to mention what the perk does. So for me right now I've chosen the smelting perk which uses 10% less material to fill the cast. So it shows xxx/230 metal poured. But it starts looping from 200 and i think the last number i see is 228 then goes back to 200. And indeed it dupes the metal I have in the crucible with every loop. Hope this helps. Other then that, man this is an amazing mod. I've been playing vintage for a week now, 2 days ago started a new world and included your mod in it and i absolutely love it. Thank you!
