I experienced a few bugs in this. When fighting Cynthia, if she knocked me back with the ground pound while i was firing the sword beam (horrible timing, i know) I would then no longer be able to move and she wouldnt be able to hit me anymore. In the same battle I found that if i killed Cynthia towards when she was at the end of her charged explosion but hadnt slammed down her hammer yet, she would get stuck in the exhausted state and i would no longer be able to do anything.
