I'm quite new to dwarf fortress and trying to make my way thru it. I read most of the utterly newby guide and want to go. Now, I'm trying to make the preparations. In the item menu, it seems that i cannot take an Iron anvil with me. I know I have enough points but the anvil just won't appear in the menu. If i free 300 points, I can get a Steel Anvil tho. What's happening?
