1. No info on swtor.spy so I thought it's bugged. You should give them a solution:
http://www.swtor-spy.com/codex/gree-hypergates/70606/
2. Btw put "(Knight)" in Darth Angral persons of note codex entry, because it's only for Jedi Knights
3. I was searching around every togruta npc, killed all togruta mobs, did Nar Shaddaa heroics and nothing. I give up, but perhaps I missed something. We know one thing: if it's available then It's in the area/planet unreachable for republic players.
Patch 2.3 doesn't fix any bugged codex entry.
