During the final conversation with Suronii, after convincing the Orc and Khajiit to join, there is no longer any option to refuse to sacrifice yourself. I had completed this quest before, but I noticed the dungeon was black on my map, so I went to investigate (I finished the zone some time ago and I'm vr5 at the moment).

The quest [Soul Survivors] was available again, so I've ran through it to the end part, and now I am being forced to jump from a cliff or not finish the quest. Last time I was here I could say no to them, and so they would attack me to try to force the issue and make me sacrifice myself whether I wanted to or not. But if I beat them then they were stuck and the Daedroth in charge congratulated me.

That's what I did before, and I'm very upset this quest is apparently being redesigned to force the player to be a dupe and kill oneself for the those random captives to leave. They probably had it coming anyway, since usually these towns get sucked into Coldharbor when their leaders make short sighted deals with Daedra.

I'm just going to abandon it. I beat it the right way before it was broken, so whatever. I hate having quests available places and not doing them.
