My wife has 10 Villagers on her island. Today Isabell announced that there was a new villager at the campsite. Sure enough, there is. I thought that you had to have a vacancy and an empty plot of land to get someone to show up. Is there any risk of this new person booting someone out and taking their spot without her authorizing it? She likes everyone she has now. I also have 10 on my island and have not had this happen.
