I dont see it, are you sure its on the free version? Is there somekind of event that I should see? There is no kind of red arrow at the bottom for the moment
the town was added in v0.23.1 and the current download is v0.23.2 so maybe its just not unlocked for you yet
i cant remember how it was introduced in game but if you updated you might have to start a new game
sorry not sure
