Cannot enter ceremony of eternal bonding

[chellyshou]

Me and my partner are having troubles entering the Ceremony of Eternal Bonding.
Our registration was scheduled this Tuesday morning at 2:00am.

What's happening is that every time we click the "Proceed to Ivory Chapel" for our separate dressing room, we automatically sent to the entrance of the Sanctum all over again. We equipped almost everything, finalized arrangements, and still nothing happened. 20 mins have passed and we're still stuck and the NPC is still on.

Update: We missed the ceremony; asking us to do reservations again...
More Info:
-Me and my partner live on the same timezone
-Arrived almost an hour early before the wedding to double check (Mrs NPC is still kicking us away from the chapel)
-We have our blank invitations in our Inventory
