Iron and Steel have very different properties, are common knowledge in the most basic of properties in the real world, and do not seem like they are just careless typos of one another. Mithril, however, has only one commonly understood idea, which is of a fictional miracle metal. I've never heard of Mithril and Mithral being two separate metals, and so having the both of them seems like it was a typo, which caused a problem, implying a bug.

That said, now knowing that the two metals were intentional, or rather, that one of them was not unintentional, it seems rather redundant to include both, and/or unobvious to have them named in this way, breeding confusion in cases like this. I would apologize if you took offense, as it was not my intention, but I stand by my statements. Please do not be overly defensive.

Unfortunately, for all the neat things the mod introduces, it breaks many others. The most notable being that it adds two types of Mithril: Mithril, and Mithral. This seems rather innocent enough until you have a dwarf in a fey mood screaming for Mithril, and you only have Mithral available.

Novel idea, but it seems to be incomplete, as some portions of the pack do not work. Most notably, Training Dummies. They just sit there and do nothing, nor can you select any tasks for them. If there's some sort of complex instructions for getting them to work, you should probably include that in the file next time.

Orcs siege regardless of population, it seems, and at an exponentially high amount of invaders. The first year was 10 orcs, vs my just gained 10 dwarves. Second year was 45+ Orcs against 30 dwarves, and the third year was a staggering 60+ orcs against 34 dwarves. The last two included Elite Bowmen and Macelords, as well as Hammerlords, making the difficulty spike.

Goblins seem to have been completely overwritten, instead of incorporated elsewhere or alongside Orcs. They disappear from the world, with no fortresses, and never show up at the fortress.

The Adamantine Golem, despite being made of Adamantine, always seems to die very early in World-gen. It needs a damblock upgrade, proportionally.
