I just did that quest but did not receive the codex entry (as a Jedi Knight).

I was definitely in the right room. But after visiting it later on after I god my space ship the chair was finally clickable. Any update on the missing "Jedi Weapons" entry? @pioneerraptor: Any response to your ticket?

Regarding the codex entry "Rebuilding the Jedi Order": I checked that room thoroughly, but I couldn't click on any chair. A page on SWTOR Spy says "Class: Jedi Consular", and I'm playing as a Knight, so maybe that explains it? I need 4 Lore entries altogether, but you listed 5; and 2 of them Consular only? Seems strange o_O Oh, and I didn't get the "Jedi Weapons" entry either. So, any help on how to get those would be appreciated.
