No, but nothing else in my town was affected. I have no weeds and my villagers/Isabelle didn't act like I was gone for a long time.When 2015 came around, did you remember to put the year back to 2014 on your 3DS clock?
Is it possible that she was "voided" to another person's town if I went over someone's town to trade? I didn't think that could happen until after the villager was gone...
