Don't know if this is a known bug or new to 1.01. Upon the start of a new Pantheon Tournament, should you decide to switch sides, the game will still have selected the last DG you used from the previous tournament. In my case, I was FoL and decided to go FoD only to find that Sedna was still selected. The game had no problem with this and launched me into a match with her.
At this point I could choose to stick with her for the remainder of the tournament which obviously defeats one of the central themes of playing Pantheon.
