Hi Great Architects! First of all, thank you for your support and patience! Here is a list of little fixes and additions that I made in the last days. [list] [*] Fixed the bug of quitting from the throne room that load an old map. [*] Three new market export cards have been added: wood, stone, and metal. [*] A button to load games from the tutorial has been implemented. [*] A button to unlock the 60 fps cap has been added. [*] A bug in the tower artifact that prevented stone buildings from being placed on brick has been fixed.
