Version .34h is up at DFFD.
Try installing the latest version and let me know if the issue persists. I suspect the DF update overwrote the default material template and took the reaction class out of wood
Im goin to try this new version, keep up the masterpiece work of this mod!
but as i just logged in after a long day of work i will report that wanst working for me in the last two mod updates, and for each new update you do, i erase my current DF folder, copy again my untouched vanilla (recently updated to 34.06) instal your mod, and install phoebus (and my custom set of colors)
btw, i think that you dont have to remove it, as it is just a thing that nobody has to do if you dont want to be cheap (like equipping a massive ammount of shields) but you can make weapons and armors from any metal that you can get... is not a big deal as quality of steel of even the blue metal is something you have to work to get, but you could do easy gold blocks from coins, and make golden wips (or even platinum if you happen to find such furniture in abundance)
aaaaaaaand, another thing that i have to report is that you could use a LOT of different things in a reaction, and all transform to first item selected. ex: 1 gold coin + 499 copper = gold bar, 1 gold bar + 3 (or more i dont remember well) any metal bars = gold forged item
im not sure if you make a reaction for melting bolts or arrows or some kind of ammo, but using this you could potentially transform any kind of metals into others
sorry for my poor attempts to write english, and thanks again for the great mod
