In the blacksmith structure in a village, both furnaces are missing a front face like a typical furnace placed by the player. The top, bottom, back and sides have the correct texture but there is no front face on any surface. We expected the blacksmiths' furnaces to be the same as any other furnace and have the front face on the side facing outwards from the structure.
