If you didn't load the mayor or any existing villagers they shouldn't plot anywhere. If you go back to time to your last day played, it should act like no time has passed. If you go back a day before that or a day forward, then the plot will show up somewhere. Don't fall for the load screen plot either, it can change and not be true to what the menu shows it as.
You didn't happen to load/save any of your characters from the last day before the voided villager have you? If you have a spot open, I would create a new villager. Just to be on the safe side...
