No, you can just reach it from two different paths, one that is initiated from Igor and one initiated from Anastasia.
Them drinking together eventually leads to the same scene in her room. So that's why you seemingly need to "respec" (You don't just two paths that lead to the same ending)
Did you move to Anastasia's room as soon as it showed the prompt? Just making sure it works at all
Understood
I see, maybe there is a bug and I'm just gaslighting myself, I'll check it out later
