...And for some reason I can't beat Vampire Hunters anymore, what the fuck. The times I hate this game the most aren't the missions I know I can't beat, it's the missions I've previously beaten yet for some reason I can't anymore.
Got angry enough I spent an SC just to restore Charisma and tried again. Used a different strategy that I'm pretty sure I'd tried before... and 3-starred it this time. Now I'm just confused. On the bright side, that's all the stars I need for this event, now back to less frustrating maps.
