In the Central Ruins, you can walk through the inn tent behind it. https://ibb.co/tYR0rr3
Before I talk about the next bug, in the dev room, you should update this gift box to not only to add an additional option to receive all Christmas items like the frog with the masks, but to also update where you teleport to go in the Gingerbread House exhibit instead, because you can't enter the exhibit on non-winter months. https://ibb.co/0Zx8Tch
For the next bug, when I Gingerbread House to check to see if the previous bug was fixed, I checked it without having Luci recruited, and still, she appeared in the house.
By the way, it's a neat touch to have a present for a certain party member not appear if they aren't recruited.
