While adventuring through the worlds of Star Wars: The Old Republic, the player can make various discoveries that are saved in your Codex – an encyclopedia type journal of “important” terms, people and aliens you meet and things you see. Lore is a subsection of the Codex. It is different because there are two ways to get entries into the Lore section. You get automatic entries by killing some creatures or visiting places, but there are also Lore Objects, scattered all over every planet, that will provide you with additional lore entries.+

There is an achievement in Star Wars: The Old Republic called Galactic Loremaster. Unfortunately, the achievement and accompanying title were made obsolete with the 4.0 update. That is because one of the Lore items – Makeb’s Mysterious Survival – was removed when the purged the Staged Weekly Mass Exodus missions. They had a rush for the players to finish that quest so they could still get the Galactic Loremaster title, achievement, and a gift. (On that gift . . . we’re going to circle back around to that later.)

I didn’t even know about the purge until last night as I haven’t been to Makeb in quite some time. I know of the Galactic Loremaster achievement but not that it was unable to be acquired anymore. But wait . . .

I have that stupid quest completed! Luckily, I had completed the Mass Exodus missions before the purge. I just hadn’t completed the quest for the other Lore objects.

Could I get the achievement and the title even though I’ve been told it was removed from the game?

You’re damn right I could. Acquired less than an hour ago, folks.

Remember when I said I’d circle back around about the gift? It’s a decoration called the Makeb Gazebo, If you’re interested in such things, it’s pretty nice. The achievement was the only way you could get this thing. I think I have an argument that I deserve this thing. What do you think? (That's the question, folks.)

Update 04FEB2019:

I had to re-add some of these pictures due to a Photobucket purge some time ago.  I also had some of the information wrong about the Gazebo mentioned above.  It wasn't the Galactic Loremaster that a player had to complete.  You see, that was a whole other line of quests you had to complete before they were removed from the game.  DP mentions some of this but here's a relevant quote found on the 'net.  Quote

All players who complete Making the Connection and/or Well Connected achievements before they are removed will be receiving a Makeb Gazebo decoration in the mail around the time Game Update 4.0 launches. If you don’t have those achievements but you are looking to get them before they are retired, now is the time! We’ll see you all on Makeb.

Oh well.

At least I had also picked up the Datacron Master title as well at the time.

Although I'll have to pick up the new Ossus datacrons at some point.  (Wouldn't want my title to be a lie, now would I?)
