So my Wind-up Bahamut code has already been used...?

[Cigaran]

Well the code was invalid the minute I typed it into Mog Station. I just wanted to show proof that my code was invalid and also to show that all my register codes were listed but with no Wind-up Bahamut input, meaning I couldn't use the code and obtain the item.

Have you tried swapping out any 'B' for an '8' or vice versa?
