This is turning into a Scooby-Doo mystery lol Here's what we know:
1.) I went to Blues' town to ask Bruce to move to my town. He said yes.
2.) Maybe 15 minutes later I went to another town to ask Lopez to move in. He said yes.
3.) Lopez moved in the next day.
4.) Yesterday Celia was in my campsite and refused to move in even though I asked multiple times. It's almost like my town thinks there's already a 10th villager.
5.) I've come to the conclusion that Bruce actually did move in and is just invisible...
