I appreciate your reply. The issue occurs if one clicks too swiftly on the “continue” buttons at the bottom of the screen once a battle is completed. The current work-around is to let one screen fade completely before clicking on “continue” again.
This is admittedly not a serious problem to avoid. I only encountered it because I was a bit too impatient when I lost a battle, and wanted to move past it and on to the team selection screen as quickly as possible.
Quirky, strategic, entertaining game. :)
