Well good news, mine got fixed I had 2 tickets open in the mission category for this problem, one since the 24th of november and one since bioware posted on this forum to ask them in a ticket to manually restore the quest. The second ticket got a hit today (By CS Dan) and had the quest "Dead Center" added to my Warrior's quest log. So thank you Bioware!

I've only encountered the problem on the 24th, the patch on the 25th fixed it for everyone unless you did it on the 24th.

My ticket's been up since the 24th of november, when can we expect a reply?

Nope I checked the orbital station and every terminal I could think of, the quest is just not there.

Same problem on warrior. Here's to hoping they work through that writhing mass of tickets soon...

This was my first thought too, but darthhater actually has her LS conversation options logged so they should exist somewhere in the game files: http://db.darthhater.com/quests/1889/locate_the_enemy/ Also, So yes I still think it's a bug.

Still happening May 9, with the same graphic glitches you describe. My ticket got the 'Your case has been escalated to one of our specialized teams' reply so no idea when this will get solved unfortunately
