It's a little frustrating that none of the Developers have responded to any of these things. The in game ticket system is also a bit flawed, seeing that you always get a pre-formatted response with no ETA when things will get fixed.
Not to want to raise an argument here, but if it isnt a bug why they should say anything? its up to you, or us to find the lore :P they dont need to tell you where it is.
What is buging me is i got all datacrons on taris and the codex is still 4/5... and im positivly certain i got all 5.
