After obtaining the Cataloguer emblem it will not leave the postmaster. If you keep it in your emblem inventory it will stay there. If you try to store it from the emblem menu, or store it from the postmaster it will infinitely spawn at the postmaster each time you load up an instance of the tower. If you stay long enough in the tower after storing it from the postmaster menu, it will spawn back after at least 5 minutes. This is troublesome because I like swapping between emblems in strike playlists to receive the Nightfall completion bonuses from their respective emblems, but am forced to have a slot dedicated to the cataloguer emblem if I don't want the postmaster to always have the notification for "finding" the emblem.
