Major issue with locations (tavern in this; probably library too, not sure about temples - but all same problem)!
I had a weremammoth bard decide to visit my tavern. He is correctly flagged as Guest / No Activity (duh, I raised the drawbridge) just as any other guests. However, he wasn't like the other guests, which is why I raised the drawbridge in the first place. Upon entering the map, this friendly guest went on to kill all my pastured animals as well as other local wildlife. As he is technically a guest, I suspect him to be trap immune like the other guests too, so there's no way to try that out for me.
For now the only solution seems to be to close all inns and libraries and stuff. Do all civilizations send guests to your locations? Could I even get necromancer visitors....? That's really scary stuff! Perhaps there's something in the raws that allows races to visit other race's locations, if so, it should probably be removed for certain races, like kill-everything werebeasts that enrage, or necromancers that raise the dead, things like that.
On another note, I find it quite refreshing that the whole metal industry is still simple as of yet. It was overly complex (in my opinion) in the older version, the current one seems very nice. A few crucial additions to the industry, but not too much crazy hoops to jump through to get some plate armor.
I'm not sure about Mithril personally, it seems too cheap to get, with just 3 silver bars. Perhaps there should be some addition to the recipe (perhaps adding flux? or increasing the silver amount?). Silver can be quite easy to come by on most maps, and it does make steel sort of redundant (even for blunt weapons, as you will inevitable get Orichalcum bars from your mithril production which outclass steel for blunt anyhow). Crazy material values for metals too, I like it. Really enjoying myself so far. Besides that undead giant bird that was in my joyous wild biome within the first month of embark... Is that the necromancer's doing? I got no tower nearby, but the necromancer civ is in range.
Cool stuff, cool stuff! I do sorely miss the bloodsteel and bloodwine though
Edit: Just to clarify, I love the concept that you don't need steel to make mithril anymore, as making steel means you are very restrict on where you can realistically embark. Only needing silver is superb and allows for some wacky embarks in mountains that are basically all gold/silver ore (found lots of those sites!) without having to worry about military grade metals. Flux would seem like a reasonable addition as it's relative easy to come by (bonemeal if nothing else!), needing different metals would again restrict the embark options. So far, I see it as a very good thing that you don't _need_ iron for your military.
