Simply put: Power Plant medium, Closed Off. I'm supposed to save/rescue 15 engineers. Half the time when I walk towards them, I'm immediately transported to the other end of the room without warning or explanation. When I walk towards the engineer and I don't get thrown all the way back, the only F-key option is "Leave/Escape Forcefield". There's no option to talk to the engineer, save him, etc. I've sat in the room a number of times and mowed down Borg spawns while sitting next to Mr Engineer, while on the other side of the room, etc.
How do you do this mission? It makes no sense and a group I was in couldn't figure it out either.
Nevermind it looks completely bugged. I dropped the mission, went back, same problem. I need this mission for an accolade, but according to other people in zone, they also can't do the mission because it's broken.
There is a way to do it, there is 4 rooms for it, try each one. You can tell if it is a bugged room or not because you cannot see the force field. If you can't find a room where you can see the force field is up then try changing instance. Normally i can find a room that works, just gotta remember to look for the force field.
Defera is almost a complete write off due to (multiple) bugs, every single hard mission is bugged, one power plant medium is a wreck, don't even bother, the only mediums worth anyone's time is the temple.
