I find it odd cuss the garden only stores 40 items in a mansion.. and still members spam the garden just because its closer to the market board.
Please allow us to put a smaller market board inside our FC house so members will actualy start using the interior aswell...

Right not having it outside does not realy influence social behavior as I often see crafters craft right in front of the board...

So to not damage the social flow I advice seperating what you could buy on this market so that the exterior market allows you to buy everything, while the interior market board would only allow you to buy crafting material.
