I'm playing in 2024 and I've done all of the available artifacts. All groups are completed except for Resources. I have Beer, Bread, Cigarette, Dough, Feather, Flour, Meat, Milk, Pie, Steak, Wheat, and Wool. I have no idea what the thirteenth thing could possibly be, and it seems like I have to 100% episode 2 to unlock episode 3. Does anyone know what I need to do?
