Oh ): That sucks, I really wanted to participate, but last time Coco and O'Hare (my two "done" houses) got something else in their houses, it took me SO LONG to change that back.
With Coco I didn't even manage to do it, she changed one of her bonfires for a fossil. O'Hare took forever to get the perfect house, and he has way too many exclusive island items for me to mess up (which I already did, once, and it was hell to fix).
He changed his old sand castle for a tee.
I also remember that took me more than a year to make my old Deirdre to change a stringfish I gave her for a bed.
Should I be this picky with villager houses? Probably not, I know, but it makes me unhappy seeing their houses all ugly! ):
