Sorry, what I was referring to was different players trading in tickets/buying items from the same Saharah, which was leading to the weird behavior Kadath ran into where he traveled to an island where she was supposed to be handing out Volcano floors but he got something different.
My gf and I share an island, and I can definitely confirm that the rugs are identical across players. But either the bell-purchased or ticket-earned wallpapers/floors are different, and I still can’t remember for sure which, hah.
