This didn't occur while I was playing Peacock's origin story, but it's still related to Peacock...
I evolved my bronze Peacock (Rerun) to silver. I then tried to take her into the Medici prize fight. She didn't show up. She also got an interesting new color scheme for her icon. I tried to capture video... It didn't turn out well.
I've been having problems when leveling up... I don't know if this is an extension of that since this is the first time I've evolved a character. When I level up, I often have to restart the app for the game to show my new stats. Sometimes it loses the level up progress altogether.

Thank you for releasing the origin story path and Beowulf!
