Oh, and of course the game clearly misses some necessary dialogues/interactions. I find particularly annoying that:
1.
I robbed and killed Raphael in his own house, killing also all his servants and a lover on the way, all 9 hells are talking about it, yet there are no interactions with Mizora.
2.
We can leave an astral prism in Shadowheart possession till the quest at Githyanki Creche. She is very protective of it all the time during all dialogues. Despite that, during said quest the prism will "magically" move to your MC (to be honest, it will move the first time you dismiss Shadowheart from your party, if I recall correctly). Aaand... Nothing. No reaction from Shadowheart, not immediately, not later. Never. You'd think such an important plot element would have at least minimal comments.
Another bug regarding Raphael:
Hope can be killed during the battle. But she is considered an ally, so you can still resurrect her with a scroll or a spell. All dialogues goes normally then, however, the quest log states we failed at saving her. DESPITE that we can still have a dialogue with Karlach about Hope creating a place to live in Avernus.
Hi, just reacting to your 2. : I did have an interaction with Shadowheart about the artefact suddenly being in my possession. Just some short exchange telling her that I did not steal it, that it just came by itself and she was like: yes, it has it's own mind, you can keep it now, but I will want it back later....
I think trigger for this is not having Shadowheart with you when you travel to goblin camp for the first time - there is this cutscene where the artefact protects you... In my 1st playthrough I had her with me and have not seen that conversation later with her, but in my 2nd playthrough I did not take her with me, the artefact just appeard in there and then we had the interaction in camp.
