Thanks. One more question...How can a villager suddenly not move without you convincing them to stay? Sydney was supposed to move out on the 13th, so I TT'd day by day to the 13th to get her in boxes and then give her to someone else. But on the 13th, she was wandering around outside. I then went to the 14th, and she was still wandering outside. Then, another villager said that someone else was thinking of moving. So, Sydney decided not to move after I told her to move. Maybe I did something wrong, but I don't know what I did...
It was another villager's birthday on the 13th. Sydney wasn't at the party, but could this have negated her moving somehow?
I don't think that birthdays negate moving.
Sometimes villagers just decide to stay, I think it's a way of giving people a second chance if they accidentally move out a villager but it can be annoying. Did you talk to Sydney at all? If you talk to them, if they're reconsidering they'll usually tell you about it so you get a chance to tell them to go.
