I've heard of this. I'll be testing a kobold embark and a dwarf embark today... I will check for access. the hardest problem is that if you can't reach any cobaltite then you can't dig down into the earth to hunt for it, unless you were enabling digging (I prefer the slade out no digging version of Kobolds, but you can't run that script and run any other race on the same world map, unless they fixed that...). Bonemold is not strong enough to make an anvil out of, neither is cobalt. You would need at least iron or bloodsteel. So it looks like to me they need a fix that allows them to build armor and weapons from the metals available to them without compromising on the spirit of what they are allowed to access. I'll see if they can make an anvil strength material. If they can, I don't mind producing an anvil reaction for that material at a shop. If they can't then the option is a cold forge type shop, something heavy struck against something hard. Anvils aren't hard to code, its 3 bars of a metal for 1 anvil... but the game wont accept invalid anvils for shops (your artifact legendary zircon encrusted wood anvil will not function, lol).
