I've begun playing Illyriad, and I'd like to produce some livestock for leather. The obvious place to produce this would be the Common Ground.
The Common Ground is an ancestral right for your citizens to graze their cattle inside the city walls, producing livestock for your City's Saddlemakers and Tanners to turn into useful end products.
But when I try to produce some livestock using the production tab there I get the following message:
Unable to start Production! You do not have the building necessary to produce this item.
What building do I need?
