ok so here ill try to explain this the best i can. today i was out collecting streetpasses and my plaza population counter refuses to go above 2799, i got like 10 NEW miis and the count won't go up, streetpass tags increases like it should but plaza population stays the same, i went to the very back of my plaza and saw that about 10-20 of my oldest streetpass miis are gone!!! it didn't even take just the spotpass ones, it took my streetpass ones!! for every new tag I get it is deleting one old mii. it shouldn't be doing this because I have seen people with over 3000 plaza population and there is an achievement to get to 3000 so it doesn't cap out at 2799. why is it deleting my miis, im really upset because some of those miis were special to me. I checked my SD card and it has 1700 blocks of available space ( also I have streetpassed people when it had 500 blocks before so space shouldn't be an issue ) but could my SD card be glitched, all my mii plaza games and everything else on my SD Card is fine, its just my miis it is deleting, why is it doing this and does anyone know how to fix it?
