Also (I didn't think this was as clear as it could have been in the notes) when changing plot size. I.E. small to a medium or large, if you have a skin on the house (I.E. mooglecottage) it also carries over the skin to the new house. We missed out on a shirogane large but managed to upgrade from a small to medium in the mist and it retained our moogles house after the upgrade.
