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?
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.
