Update: Rococo furniture has been set up upstairs. Hopper is going to be moving into my town tomorrow. Guess I'm gonna have to time travel a lot less, or else he'll move out. Anyone have tips for keeping him in my town? Since I don't know too much about all the information, if there's some special information for when a villager will move out or something.
here is a link to a villager rumor guide. When you're timetravelling, just talk to a few of your villagers really quickly until you get something out of them. It can be tedious, but it's way worth it. And if someone does move out, someone here will definitely hold them for you!
