Some Minion Codes Expire, Some Don't on Mog Station

[Darkflare]

Please don't flame me, but I feel I have to ask as a collector and I'm sure others can sympathize. I've been attempting to collect several of the hard to obtain minions. Recently, I picked up a few of the old blu-ray soundtracks and to my surprise, despite the expiration, some codes work and some don't, while support can help with some while they can't with others. For example, the 2016 Before the Fall album included the set of primogs, but the code still works. I recently managed to find a rare, unopened copy of Before Meteor and it included the Dalamud minion code. To my dismay, support said they cannot issue a new code for it despite it being valid. While I understand in a way, the inconsistency of validity bothers me.

Is there any possibility the developers / Square-Enix as a whole would consider a way to redeem or reissue a valid, yet expired code? I voiced my concerns to support, but it seems to have fallen upon deaf ears.
