I first tried this quest with my Engineer a month or more ago and remember reading at the time it was bugged. I too wasn't able to get my away team to travel through the transport devices, but I was able to complete the mission using a lot of cover shields and hypo sprays. Now I'm cleaning up old quests on my Tac officer and sure enough, my bridge crew stops following me after the third transport device. Even better, I can't activate the last device, but I think that's because my security escort finished off the Hirogen after I was incapacitated.
And yes, I did file a bug report (2 actually), but I wanted to post here to see if my case was the exception or if it was never fixed to begin with.
Im currently lost being a new player and trying to find which sector block to drop off my medical supplies for the O-X DS Relief effort. No intel in captains log. Please send guidance, i have too many missions and my brain is fried!
I just did this a few days ago and yes it was bugged, after I transported to the final test area I had to fight solo. I was able to kill the two-three groups barely and get back to my away team, which were just standing around near the previous testing area.
I think it might be that the jump to the last area is so far the NPCs can't follow, so they just give up and wait.
