I seem to think this has been mentioned as an issue before but yesterday I let NotB autoplay while going for the grind goals and I kept getting notifications that it had failed. I then watched it a couple of times and when The Beast used his fury move in his final form my characters were sometimes being hit with Doom despite having an Astra on the team, triggering a fail if the Doom counter hit zero on my Eddie before The Beast was killed. I double checked and in none of the runs I watched had she been killed and revived, which I know disables passives, so that wasn't the issue.
