I found one glitch in the beginning when I first started training. I hit the warrior in the air and he froze there. I think it happened because I wasn't completing what the tutorial was asking at that moment. Instead of evading (R stick), I was just messing around to see what kinds combos you can do.
I think I either jumped or evaded, and the warrior unfroze. Hope this helps. This game is awesome!!!! Love the kill scenes.
