[spoiler]Victoria is in France but Constance sends letters. Fixed latest patch.
Even ending with more than 50% approval from England and Austria the end still speaks about the war.
And this one I found after the update: When I talk to Constance about the assassination attempts, even just romancing her I win the achievement for more than one romance.
I do not know if that would be a bug:
If I convince the emperor about the marriage of Alex and Vic and make the brothers understand each other, with Franz giving up the title, the game gives priority to this and not to marriage at the time the emperor speaks, so I do not win the bonus support with England.
