As some of you may know, the codex in the game is horribly bugged. As of right now (2/15), none of the planets can be completed for many of the classes. Bioware is probably aware of the issue, but unless we make it known to them that it should be a priority, they'll probably keep delaying fixing the codex. To this end, I'm making a petition that you can just copy and paste into the /bug command in the game to let Bioware that we want the codex fixed. I've made it so it lists all the bugs and still fits within the 2500 character limit.
(thanks to Anduni and everyone else who contributed to the thread that collected the bugged entries at http://www.swtor.com/fr/community/showthread.php?t=104803)
Copy / paste from below:
We find codex completion to be a viable alternative to end-game PvP, flashpoints, and operations, but as of now, the codex system is fundamentally broken. Please check whether the following codex entries are either bugged or missing (* indicates the entry is bugged for only some classes.):
