When "Having my arm tested" i accidentally used magic and vilkas quoted "what do you this this is? we don't use magic here. Now come at me!". So i brought out a short sword and proceeded to attack. except after knocking him out 8 times he just keeps saying the same thing over and over. I've left the area a few times, tried talking to him and always get the same results. Any way to fix this or is this a known glitch?
