I haven't I said I agree. I just said I understand the notion to make certain decisions final.According to dev's vision maybe but I totally disagree with that. All games should be full rollbackable.
What happens in reality when players want to have choices... They save again and again and load a previous game if they don't like the choice they made. That means it's always possible to reverse a bad a choice but blocking rollback just makes things tedious.
At worst, this thing could be linked to a parameter.
It can improve the game if it's done right. But this is not so easy.
But here I can roll back and fore through the dialogue until I have to make a decision.
Then I cannot roll back to see what the decision is about?
Meanwhile I ran into several "Accept/Refuse", "Sure/Nope", "Yes/No" decisions.
In the end I spend a lot of time trying to find the accompanying dialogue in the sources to figure out what I was about to accept or refuse.
So I decided to end this experiment. Delete? Yes! What was the question? Dunno. Cannot rollback.
