Techno

created creative world, and started going mod by mod. it was the more medals mod. I'll be leaving a comment there.

Yes, I can replicate it. I actually deleted my first cast of the copper pickaxe head, since I tried to break the mold to get it. as for the mods, None that expressly state the change metallurgy. My best guess is a mod that adds new metal types like titanium... other than that, theonly thing related to actual metallurgy is that helve hammer extentenion mod, and I highly doubt its that. I also have a couple out of date mods, which just didn't have an updated version, but all the comments on those say it still works for the current version.

I don't think that worked, it might've worked if the mold was still hot, but not sure I can do that

attached is the screenshot you requested. I already cheated in the pickaxe head, explaining why it's blank. the ingot molds are the same condition as the hammer mold, but if you need a screenshot for that too I can.

So I pour molten copper into the fired pickaxe mod, let it cool, and then no combination of button presses lets me pick up the pickaxe head. tried it out with the hammer and ingot molds as well, and same problem. I physically cannot progress without cheating in the head, and destroying the one I poured out by breaking the mold.
