Okay, I've seen some others have similar problems. In Act 3 after the harper ambush, Jaheira leaves my camp to find Minsc. As I play through Act 3 I uncover clues that Jaheira is a shapeshifter. But I cannot find her, in any form. I get to the counting house and finally see her as a shapeshifter. I go after her and Minsc and, this is where it is seemingly stuck. I cannot save Minsc. Jaheria isn't in my party nor my camp, and hasn't been since the lower city. I believe this part is a bug. With Minsc I have tried every combo to save him, but the emporer never does. Looking online EVERYTHING simply assumes I have Jaheira in my party for this fight and i can recruit Minsc with her. At the same time, there are people on places like reddit saying they recruited Minsc without Jaheira. Again, no real details, just that she isn't in their party.

What i don't know is if real Jaheira is still alive and where to find her if she is. She just left my camp with no option from me and i literally have seen her since. So if the real her is alive, i can only assume i have to find her somewhere.. if this is the case.. where? If not, how do i get Minsc/ The Emporer to calm down? The Emporer sounds like he skips a dialogue option in the cutscene. If this is the case, how do I convince him to protect Minsc? I spent 2 hours trying to figure out how to get this to work. I had skipped 9-fingers so went and talked to them.

Basically this:
Is real Jaheira still alive? If so, where can i find her? ( her completely vanishing and never returning does feel like a bug i have to admit). If she is dead, where can i find her body?
Can I recruit Minsc without Jaheira? Am i missing a dialogue somewhere? It's the Emporer seemingly not protecting Minsc, is there something else i have to do to convince him?

and yes, i use non-lethal

Any details on this will be helpful, i have found lots of contradictory stuff. And like i said many walkthroughs simply assume Jaheria is with me in this fight. I have no idea what to do.

This seems to be the second set of options that feels skipped. But again, this is assuming Jaheria is with me. I never get these options. Copy and pasted from one of many walkthroughs:

Jaheira wants to save him, but the Emperor Mindflayer thinks he's too chaotic and would disrupt your plans. Choose the following replies if you want to recruit Minsc in Baldur's Gate 3:

"Try to protect him. I must defy my urge."
"He's Jaheira's friend. Do it."
"I don't think you want to find out," or "It doesn't matter--help him."
