This upgrade asks for extra buildings
@Nekobasu @KellyGrey Unless I love this new update with a new event type coming with new cards and characters, I still miss an extra furnace! And maybe an extra camp would also be helpfull. With the new cards the use of extra steel grows more and more. Steel you have to steel or wait on the cards, but now is the time to help us to make more steel. Hope you finally give us a bit extra steel which we need so badly!
