Hi, I'm not sure if this is a bug or if this is going to be an issue in Act 3 (currently playing Act2).
The thing is that in Act 2 when I get to
the shadowfell in the gauntlet of Shar I end up having to fight Shadowheart after trying to convince her not to kill the night song. As I didn't want to kill her I switched to no lethal attacks and win the fight.

But after this it looks like the artifact that she was carrying is missing and I guess it is important for the story. Also some of the other companions act as if she was still in the camp with us.

Will this become an issue in act 3?
