I can't help but be disappointed that no attempt was made to increase the output of the Mineral and Open Pit Mines so we could produce enough sheet metal to support the new facilities. Looks as if once again, I won't be able to buy anything that uses more sheet metal.
Why don't you just put more mineral and open pit mines on your farms? I have them on i think its 9 of my 14 and have 3 metal plants that i can keep stocked.
Happy Farming
