Larian Studios Forums Baldur's Gate III Baldur's Gate III - Technical & Gameplay Problems I was never given the opportunity to save the Duke

I think it may have been bugged for you. For what it's worth, I never attended the Coronation either (mainly because I was metagaming figuring it would be the catalyst for a forced chain of events within a certain time limit and I wanted to take my time). Even with never seeing the Coronation, I was able to rescue the Duke from the Iron Throne.
