This isn't truly a bug, just something that is highly inaccurate.
I had just joined the Twin Adders and then my link pearl pinged and Milfinia(sorry for spelling issues) said that I should go back to see the Scions and that "just because you're a Flame of Ul'dah now, doesn't mean you're not a Scion anymore."
Just thought you should know that the text is slightly off there...
Otherwise, game is great!!! :D
