Having the same EXACT problem. Weird thing is, I played through it with a level 70 Guardian a while back and everything went fine. Now doing it with a level 70 Juggernaut and completely stuck. Out of the blue. He's geared with all level 70 purples. Spent a fortune in credits getting Senya to level 30 influence (despite never having needed to the first time). Set her to heal, tank, dps. None of it makes any difference. The thing that happens is: My character gets stunned and WHILE HE'S STUNNED (ie UNABLE TO RESPOND), the Gemini Captain kills Senya pretty much INSTANTANEOUSLY. That never happened before, and I don't know why it's happening now, but it occurs every time.
IN ADDITION to that, a number of other really insane things have happened for me in the numerous times I've played through this battle with this character:
- My character was killed by the door to the bridge closing on him as he entered.
- My character was shut out of the bridge after Senya and the support droid entered.
- Senya was shut out of the bridge when my character entered.
- After getting killed the first time, he loses the support droid and is cut off from the rest of the ship so there's no way to go back and get another one (not that that really seems to make any difference)
I've restarted the chapter three times. Always goes the same way. I've been playing and subbing to this game since beta in 2011. I have 22 active characters, 3 of whom are in or have moved beyond KotFE. I know how to play it as well as anyone could reasonably be expected to to get past a main storyline chapter in Story mode. I've never been stuck like this with any character in 7 years of playing. It's not a lack of knowledge or experience, it's a PROBLEM with the game itself, and a seemingly RANDOM one - something that the devs NEED to fix. Maybe something that's cropped up since the server merge, because I played through the chapter with my Guardian before that. I don't know. In any event, I don't think it's reasonable to a) fault perfectly competent players for merely experiencing it or; b) require some massive payout of currency to solve it.
