Weird bug in Talus Dungeon (Story)

[hektix]

I just passed up the chapter 20-21 quest in the Talus Prison in Zaiwei and came across a weird bug. When you have to fight Kangchul and take down his barriers with the designated ice or flame weapon, I would attack him after his shield was broken and my weapon disappeared, and every time I attacked normally my character would be partially glued to the ground and my screen would zoom in as if she died for about 5 seconds. The bug didn't make it unplayable but it was quite annoying since he was constantly knocking me down with his AOE as a result.
