Got the glitch twice. At the very end of tutorial, when you have to press R1 to execute the enemy, it doesn't work. Character does the animation of pulling something from back but doesn't do the finisher. If I move further away, sometimes it brings out the chain but it doesn't connect. I've hit it twice now and both times restarting tutorial took care of it.
I had a couple bugs in this part. First, when I grabbed the enemy at the very edge of the circle, my entire character model shook violently through the whole animation. Then when I was told to fight the enemy to the death, he wouldn't attack me, his health wouldn't go down, and nothing happened whenever I hit him. I had to quit out and try the whole thing again.
