I very recently got Merengue in a trade, and the previous owner moved her out of their town. So I went a day forward on my 3DS clock so I could reset her house plot, but she was nowhere to be found. So I went another day forward...still no house plot. Another day, and after several resets, she was still absolutely nowhere to be found, even with all the open spaces in my town. I don't think it's a matter of me being impatient--is it just possible that my game glitched and something went wrong? :/
