Well, when i tried to make a short blade using tin i left it on the "Blunts" setting by accident, and it turned into a large copper hammer head even though it was tin AND only one piece of it... I am running alpha 0.0.7 and there was no error message and my specs are Intel core i5-3320M 8.00 GB of RAM. I did it once and didn't realise it was copper until i had sold it and it ate some of my money. (I would love to back this in a while because it seems to be doing really well, ill back it when i have the money)
