Cannot complete server transfer

Date & Time: 04/23/2019 & 04/24/2019
Frequency: Every transfer attempt
World name: Diabolos -> Exodus
Character name: Brielle Silverwood
Retainer name: Checked all 10
Level: 70

Steps:
I'm trying to transfer my character from Diabolos to Exodus now that data center realignment has occurred and during the free transfer period. I believe I have done all the necessary steps in preparation for the transfer, but when I go through the process on Mogstation I get the error, "This character or one of its retainers is in possession of a ceremony invitation."

I have performed an /isearch for "ceremony" and "invitation" separately but neither can find a ceremony invite in my inventory. I've also reviewed my player inventory, chocobo saddlebags, and all retainers and cannot find a ceremony invitation. I've deleted my entire mogmail inbox in case someone had mailed me one and I've spoken with the NPC at the Ceremony of Eternal Bonding venue to ensure I did not have an expired invite somewhere. I've also tried logging out of Mogstation and the game and back in again.

I even took screenshots of each of my inventories for a second review from fc mates to make sure I wasn't overlooking something. I spoke with Square Enix chat support earlier yesterday but they advised that since this error is regarding player inventory that a GM would have to assist instead.

I submitted a ticket to the GM team yesterday afternoon but did not hear back from them so I'm wondering if official forums can provide any further support. I was split from my raid team with the data center realignment and am currently poised to miss raid later tonight unless I can sort out this server transfer beforehand.

A GM replied to my ticket which has now been RESOLVED. I discarded a ceremony invitation months ago using the companion app but it turns out the companion app maintains a discarded item reclaim tool for the last 35 items you discarded via this method. Since I had discarded it, it did not show on any item searches but it still prevented my transfer. I had to reclaim the item through the companion app and re-discard it in game in order to complete my server transfer. I wasn't able to find a resolution for this problem through any previous reddit or official forum posts so wanted to share what the fix was in case anyone else stumbles across this post in the future.
