Hey, I really need help because I'm super disappointed. I prepared everything to marry Mark, house upgrade locket, all heart events and finally the wedding ring. When I give it, the ring is despawned, I can no longer buy it, and a normal dialogue from Mark is triggered. After about three days I got an in-game message saying it was my wedding anniversary, but there was nothing to be found on the island. Please it took so much time and now I just can't seem to marry Mark
