I don't think it is. I think I might've just skipped through the expansions without realizing.

That is a damn shame...especially since its my fault for not reading. Here is my quest list: https://imgur.com/a/YlleZ6T

I haven't played SWTOR in quite a while, and couldn't really tell you which expansion I dropped off at. I have a bunch of characters, some more progressed than others. As for the issue in question, I have a level 66 Jedi Sentinel, and it looks like my next questline, if following sequentially is Rise of the Hutt Cartel (or Day of Dread?). sub question - why do I have 2 "chapter 4" quest lines? Does it matter which one I choose? Anyway, when I go to my character select screen, it shows that my Jedi Sentinel isn't complete... what gives? If Chapter 4 is my next step in line, doesn't that assume Chapter 3, and my story quest, is complete? A clue that I haven't even finished Chapter 2 is that under my Legacy perks, it shows that my Jedi Knight doesn't have any of the perks unlocked. On a side note, it appears I have a few purple missions in my mission log that perhaps could give some clues as to where I'm at. Fallen Empire (Chapter XIII) Violent Uprising (flashpoint) The Jedi Prisoner (flashpoint) Ilum - Crystal Ball I believe I've done Violent Uprising and Jedi Prisoner on my other character, so I know what those are... just not sure if its related to my predicament. Anyway, I hope that helps solve this mystery for me. I appreciate it.
