I wouldn't say JK is the favorite, especially since Imperial Agent is the best story.

A lot of the codex entries are bugged. At least 1 on each planet in fact.

Hate to spoil part of your theory but

Don't get too happy. Each planet has multiple bugged entries that will keep you from completing the entire list for a planet. I'm up to Quesh and I haven't been able to complete a single planet yet. On Imperial side anyway.

bump Another codex entry I found to be bugged was my ship's entry. Everyone is supposed to get a codex entry about their ship when they get it but I never got it (Imperial Agent).

Why is the codex so horribly bug ridden? I like the lore in this game so I've been trying to find every codex entry on each planet, but I run into stone walls when every single planet without exception has AT LEAST 2 or 3 bugged codex entries that are unable to be accessed due to one reason or another. For example, on the starter world for my Imperial Agent, Hutta, I never got the Person of Note entry entitled "Intelligence Profile: The Red Blade". Not after killing him, not after talking to him, none of the ways you got it in beta. There is also no clicky for this entry. A lot of Titles (which count as codex entries) are bugged too. I never got the Conqueror of Balmorra title when i was supposed to and thus couldn't complete the codex list on Balmorra. You also can NEVER complete the codex entry list on the starter world you didn't do. Your list contains codex entries that can only be gotten when you accept/finish quests and you can't accept quests from the other starter world. It would be nice if Bioware fixed all these broken codex entries so completionists like myself can actually get them all.
