all 5 engineers were still alive, but the mission failed.
Filed Bug report #1,170,275
Yup and i was in that group. all our eng were up and happily typing, after we got our fail. noone lost a console. IIRC we tried 3 times. Had the same thing happen in the morning on my klingon, but only once out of 6 tries. Yes we quite trying .....
Ran it Tuesday evening and we beat it pretty smoothly. Especially since it was my first time every trying it. Had to redo the hiccup with the scanning and protecting the engineers. Basically boiled down to someone must have scanned an undine by mistake and thats why the respawn was higher. Switched tactics to let tac's with escorts cover the far ones and the closet one for the added firepower. Then sniped backs of each other. Just, that is a really long time to sit there shooting. Could be sped up some.
Not sure if it's fixed or not. We thought we had chased down all the Undine and offed them, but we still failed the Protect the Engineers phase. However, when we swept the Promenade, all the engineers still appeared to be working and no Undine could be seen. So we were mystified about where we went wrong.
This was early afternoon US time on Sunday afternoon/late afternoon UK time.
