Doesn't look like they've made any attempt to fix the Codex bugs, but judging from the new "Legacy Achievements" system they're planning to implement in 2.0, I'm guessing they'll either tidy up the old Codex, or just get rid of it completely and port over our existing unlocks into the new system.
Info is on the main news page of course, but here's the link anywho: http://www.swtor.com/info/news/blog/20130403
Guess we'll find out later in the week. *Fingers crossed*
I have early access, (big whoop) and according to the patch notes the ONLY thing done to fix the codexes was to correct typos in the text. Comfirmed with on-line play, and just to add insult to injury, there are achievements that can only be achieved by gettin the codex entry. I am sure about the rest of you, but I find this lack of professtional pride quite infuriating. Honestly, letting these bugs go on for so long and largely ignored, speaks volumes about their attitude towards quality control.
