Every time I do a TRNM or any dungeon needed for the "[Event] Manahan's Nemesis", I'll receive a "[Event] Dungeon Insigna" in the parcel post; the problem is that after you get 5 of any of the "[Event] Dungeon Insigna" you can no more read the parcel post message (because it said "You can't hold another ...), but for the server transfer you "must" open and read every message in parcel post.
It's an unexpected error, or you're planning to change the server tranfer voucher a make sure it'll be usable even if there are some messages to read ?
Beacuse if is an error, everyone who did more that 5 times the same dungeon , won't be able to change server at the end of the server ^^.
