What of those of us who can't get missing pieces of the Cross Light Wings outfit through the event because it thinks we've attained them all? I've never had the floor or background items and it says I've claimed them all, likely because I made pieces that come later in the chain through the design studio. You should still be able to get them through the event like everyone else, rather than have to make them (the materials are astronomical), as I've never completed the set, regardless of what the game thinks.
Thanks.
