Hunting Grounds Mission - unwinnable fight? [Act 4 spoilers]

[Beleraphon]

I appear to be really stuck on this mission. I've killed the Haemonculus and heard the message on the vox as I was leaving its base. I return to the village and meet Caligos Winterscale and his retinue. I've tried every dialogue option and it always ends up in a fight. I can last maybe two turns at most, as Wintersccale and his retinue are super overpowered.

I've seen videos where there are Eldar in the fight (I resolved the earlier stand off peacefully and helped them) but no sign here. Also the auto saves seem to have all been taken up after I arrive at the village - so I'd have to go back and fight the Haemonculus again.

When I hear the distress call on the vox it gave me the option of staying in the facility instead of returning to the village - is that something someone had done?

ive honestly never had to fight winterscale - it plays a cutscene of him engaging in a short combat and thats it..i imagine its due to being iconoclast though.

I am a dogmatic on this run and I got the scene too, where Calligos kills Warten, and no fight happens aferwards.
My theory is that you must pass two dialogue checks with Calligos earlier. You get twice an opportunity to pick one of three checks with him, and after taking one the others vanish. I believe you must pass both of your choices to get the no-fight solution. The first dialogue with Calligos was in the village and the other on the battlefield with the aeldari.

Could be completely wrong, of course. It might as well have been the opportunities to make him realise what he has done, and the statement that the old Calligos would never have left his planets to Chorda without a fight.

Seems I'm stuck as well at the same point.
Got a peacefull outcome in the Aeldari / Calligos situation during "Hunting Grounds", went to kill Tervantias with Idira, then I got the vox message, tried to go there a few times, the fight is just ridiculous, now way to beat it (while being around level 40).

If you ignore the call, you can return back to the same fight but from a different angle with lot more cover, but Calligos's party is just way too strong, they two-shot pretty much anyone in my group. I tried to focus the "Grey" character, but could not even down him and got wipedat every attempt.

Now the "Hunting Grounds" quest is stuck for me, since I would need to complete "Answer the call" to finish it; all dialog options lead to the fight, and I can't win it, so it seems there is no way to continue on the main quest.

This fight with Calligos's party is just nonsense.
