Hi guys I recently discovered some fun stuff with untradable crafting and I made a steam guide if you want to check it out https://steamcommunity.com/sharedfiles/filedetails/?id=1548525569
I didn't even think about the fact that you can make endless amounts of untradable metal, until you pointed it out the other day. Good job on the guide; everything is straight forward and easy to follow. My suggestion would be a possible "Useful links" section, on top of having them spread out throughout the guide.
