Everytime I open my saved world again, all assembled weapons/tools are disassembled and all the blades/heads are "hot". I have to quench them again and re-assemble the weapons.
Also, I had an instance were I would put 1 tin ingot on the anvil, trying to do a hammer (which I realized later I needed 2 ingots), and it would give me a great cooper blade. However this might be intended since you can't do hammer with 1 ingot.
