Here's a considerable issue Animal Crossing: New Horizons' players will want to keep an eye out for. If you visit the campsite and decide to adopt a villager that another player forced out, the plot of land that villager takes up can end up getting glitched. You'll continue to get a message that says "'s New Home" is on the way, but it never happens. This means you can't place any other new plots afterwards, which obviously causes a problem. This goes for either amiibo or regular random characters.
It's important to note that villagers who decided to move out on their own are perfectly safe, even if they came from amiibo. Hopefully Nintendo is aware of this glitch and has a fix in the works already.
