TT by changing your 3ds clock instead of the in game clock, then you can create a new character and check if anyone's moved out, if they have then you can just close the game (don't save) And change the 3ds clock again, and stop them from moving, and then keep doing it.
This would have been helpful 48 hours ago heheCan't tell if sarcasm or not.
But yes.
If you are really worried, when you TT, talk to everyone out, tt a little more in the same day, talk to everyone again.
