I couldn't make alloys, since I turned off the Alloy Furnace, being under the impression it would leave the vanilla reactions alone. I also got a huge pile of slag I wasn't expecting because I turned off the Slag Pit. I'm hoping that turning on those devices will bring those aspects back, but it would make a lot more sense to leave at least the vanilla alloys in the Smelter and Magma Smelter if the Alloy Furnace is off. Likewise, making loads of slag doesn't make sense when someone turns off the Slag Pit. If nothing else I can dump the slag out of the way or use it to build.
I was also having difficulty figuring out how to get seeds from trees. I've been buying them, but that only goes so far. And I assume that Feather Trees are special and cannot grow in the farms? I've been using all my featherwood for bins (using alt-A to specify all my bins to be made from featherwood) and I have a good enough supply for now.
Also, I found Titanite, but I can't figure out what to do with it. I assume I need the Alloy Furnace but the manual refers to the Arc Furnace which doesn't seem to exist.
How does one get Tobacco for the Tavern? The manual mentioned 'cooking leaves in the Kiln' I think, but where do I get the raw leaves? o.O I built a tavern in the middle of my dining hall, and it seems to make the dorfs happy but they're missing out on the benefits of pipe weed.
(Might actually be a nice change if it were called Pipe Weed or something, instead)
I LOVE the fish pond. Keeps the morons from running out to fish in the river when there's a perfect spot inside the walls. I thought the Trading Goods depot was going to be lame, but it has been interesting. I like that I can buy library goods in bulk instead of building up yet another industry.
I'm actually getting decent military skills for the first time with the Libraries, but it's a little confusing because the actual book items don't have the same name as the reactions and the reactions show whether you have the book or not. (I think.)
Oh, and my first artifact seemed to take forever to kick off, but when I finally got one, it was an Orichalcum Shield made with the first bar I found. It only menaced with wooden spikes but hey, artifact shield, right?
