Oh, wow. The same exact thing happened to me, in my first town.
I lost Maple due to not playing for a while. She was the only villager I liked.
So, I time traveled a ways forward. So, that I would have an actual reason to reset.
Annnnnddd....I reset, which started a vicious cycle of resetting every town, but I'm trying to stick
with the one I've currently got, now....
