I'm not sure if this is the correct threat/topic but I just let someone adopted a villager from
my island and after she left. The villager house says "I've moved out". Is that normal or a glitch...?
This is my first time letting someone adopt a villager from my island so I'm not sure how it goes.
That's normal. As long as the house doesn't stick around after the reset at 5 AM, you're good!
