I fought Meryme in her second phase and beat her to a pulp until she does nothing but run away yet she just never goes down. I'm doing 50 per swing with my saber in some corner as she refuses to fight back and kept hitting her over and over for ten minutes until I eventually ran out of stamina. What's going on here? A bug?
Edit: A few tries later, some with berserk potion, some without, all of which ended with either me getting beaten or the bug reoccurring. Finally, after I decided to just wait out the first minute by guarding against her attacks, then popped the berserk potion and went goku on her ass, got the fight to end at last.
