Special Note: These were released by accident a few weeks ago, and many players had built, or started building this Printing Press and Post Office. A short time later during a different update, the printing press returned to the stage 1 form and we thought we would need to build it again when it was finally released. HOWEVER, The printing press that was built before this update works even though it looks like it isn’t fully built!
