HELP!!!! Basically up until last night I had 252 mii's in my streetpass plaza. I got my usual streetpass with my girlfriend last night and this appeared....(see image) ...Just a blank square, not detailing the last game she has been play. Which i've never once seen in two years of 3dsing. Now I open my 3ds to check my streetpass this morning and nearly all my characters have gone. I've just got the original 49 i transferred over when I upgraded from the original 3ds to the XL. How can i get them back. Please help. ps. Ive changed the date and time back and forth. But it seems to have done nothing (as suggested on another side) pps. I've just checked hers and hers has reset too. She's lost around 70 Mii's :-( ppps.
