" Although the player receives pieces of this set through contract #16, the player can assemble a complete set after contract #9. "

What I must do to complete set after #9 contract when I don't haveMechanicon Gravel    and  Mechanicon Cement    yet ? Can I buy it somewhere?

Sorry my english is not so good that I could understand this situation...
