So just by pure chance, my friend noticed today, that you can switch your tavern to the gilded version of it, when you are in the secret room and interact with the VIP cake.
She was like "woah, everything is golden", but it didn't change for me. Obviously, I went into the room as well and pressed "e" at the cake, which then made the tavern golden.
I'm just wondering: Is it intended, that only the person who interacts with the Cake in the room sees the tavern? I feel like, it should be
Only be changable by the host of the tavern
Have all of the visitors see your "theme"
