So I managed to get to the half-demon and lost that fight horribly. Advanced the day to evening and now Astaroth's work is available. Since I don't cloud save and don't have the game installed elsewhere I can't be certain if I experienced a one time issue in 9.1 or if it was caused by the fact that Astaroth was technically helping me up the mountain and now no longer is since I defeated the three knights and have the hammer.
