USE ALL THE METAL SHEETS INTO IRIDIUM SLUGS for Space Crafting Flight 101: GO
I crafted 2 metal sheets and R. Lochen wanted me to use them all.
I have completed the task of creating from 2x Vanadium a metal sheet and crafted 2 Iridium slugs.
R. Lochen requests for BOLTS where the right title is SLUGS.
