When i go to do den of thieves I can always find drake, but then when i have to defeat the commander i loose track of him and can't find him again, or his health goes to 0 and he doesn't die, is this glitched or am i missing something?

Nevermind i got it working now, must have been a one time glitch.

I'm actually having the same problem. I've been attacking him for 45 minutes straight and he is at 0 health, but I cannot defeat him. Happened yesterday as well - and I just logged off that time - I can't complete the mission. Not sure what the trick is to killing him.

Yeah, it bugs sometimes. I think you can just leave the mission and Continue it, or it might work that you have to walk as far away (out of targeting range) as you can get, and then come back.

Bugged here, as well, and beaming back down did nothing. I have submitted a ticket / GM help request to see if anything comes of it.
