I thought this bug only happen to me because I asking my friend in-game he said he not get the bug. So the bug is, NPC Nanon (Badge & Memory Exchange) not in her place but she is bugged into Mutan (Challenge Miles Exchange) [I sent the pic to clearly understand my explan]. Before knowing she moving place I confused search for her I moving to another block but still doesn't exist, and till I decide to surround the shopping plaza and I found her bugged with Mutan. It doesn't harm me, but still a little annoying.
