When I attempted to fight Arcann towards the end of chapter 16, I am pretty sure I encountered a bug. Everything I've seen so far suggests that when Arcann jumps to the stairs and starts shooting lightning at me, I should be able to put my shield up and just walk to the stairs; however, this is not the case. When I hit Arcann with the shield when he's at less than 20% health, he jumps to the stairs, stunning me. He then proceeds to hurl attacks at me, including the empowered lightning, at me until I regain control. Unfortunately, I can only look side to side when I regain control. Even with the shield, I am rooted to that spot. The shield also does not protect me from the lightning being hurled at me. So, I eventually die. On my last attempt, I noticed that there was a buff saying that bc I had been hit with lightning, from when I was stunned, I could not move. I do not recall how long it lasted, or even if it ever ends. I just viewed a video walkthrough, and the person on there was immediately able to put their shield up and walk towards Arcann. I can not move at all. I am lvl 65/66, and all of my gear except my main lightsaber, which is lvl 200, is lvl 208. I do not know what to do.
