Platinum Eternal Bond Bug

Time: 10:40 AM Friday 19th of December
World name: Ragnarok
Character name: Taretha Mediviere and Lunna Ravenheart
NPC name: Etoinelle
Party or solo: Party
Area and coordinates: East Shroud 17,17

Steps:
1. We tried to reserve eternal bond term since 10 AM, but Etoinelle was bugged and did not reserve almost any term.
2. At 10:40 AM she finally reserved term for us - 4AM on 27th December.
3. Only Taretha Mediviere received blank invitation while Lunna Ravenheart did not. We both had free space in inventory, we both were in party and we both had platinum bracelets equipped. We also had matched ceremonial settings.
4. We contacted ingame support, because we wanted them to return blank invitation to Lunna Ravenheart so we could attend the marriage, they sent us here.

EDIT: We deleted our blank invitations and this Friday rescheduled on 7.1. 2015. Problem solved for us.
