So, I just made a moogle mailbox for my new FC house today and after placing it, there is now a small white cursor arrow above it, pointing down.



When taking a screenshot, however I discovered when I toggle the UI display, it disappears with everything else, but then comes right back again.



I've tried emptying my mail, moving its location around...anything I could think to do outside of picking it up completely, which would of course destroy it. Anyone know what this might mean? I'm super confused as to what it could be! Thanks in advance!!

PS, I am a PS3 player...if that makes any difference
