I've done several searches and can't find an answer. How do you unlock the 37 X 37 expansion? I've completed the 35 X 35....it says "complete the enormous pain in the. mission to unlock" What do I need to do to get that mission? It hasn't popped up that I know of...or if it has, I've already done it. The only missions I have currently are the last of Fanny and Hank, the last of the Pox, and "building a snow fort" that I just got today.
