I don't really need bells, I have plenty in the ABD. I'm thinking one way to "fix" this would be to do the cycling all over again: cycle my 8 desired villagers out of Main Street and adopt them all over again, so they can be cycled back to Main Street. I'd have to cycle about 20 new villagers out of my game, and the mere thought is tiring, but it might be the only way to get everything back to normal without hacking.
