At the end of Eliwood chapter 28, during the unskippable fight between Nergal and Athos the game locks itself and ceases the fight in place. The game doesn't freeze as the music continues playing and the hp bars continue to flash but Nergal and my randomized Farina refuse to fight. I think it might be the devil axe Farina has might kill her after Nergal attacks but that's really just a guess. I have no idea.
