I stumbled upon this while making Genetech combos... the Unadorned Steel Sword fusion seems to be broken. I've made sure the ingredients are correct (Iron Ore, Iron Ore, Stone Sword Mold), but trying to combine them just gives me "Invalid Combination" errors. It's the only one I noticed that wasn't working, because I made lots of Genetech items aside from this today.

Also the item itself currently shows up as Special rarity.

There is an open topic for this but it has fallen back a few pages. Feel free to bump that one up so that they know it is still an issue! Thanks!
