I found out someone is giving away my dreamie, and I was about to ask to get her from their town when I found out that I have 10 villagers...but I only have 9. My brother tapped in an amiibo card to move in without asking me, and then saved! That was today, so she hasn't put up a plot yet, but is there any way to prevent her from moving in? (I know there probably isn't, but I'm desperate!)
