Thanks, I just updated the game a few hours ago to 0.7.6 so that bug shouldn't happen again :)
Issue is gone but that’s strange what ever I choose, affection with grace go down from 0.5 to 1 depending on the choice.
Add the dialog that I have in 0.75 to be able to search for Grace just after is not not anymore available :-/ ( I don’t think it really matters but I wonder if this choice is still accessible ? somehow )
(I have restart a game to be sure)
Yes the choice in this case if you want to pursue Grace is to pick the "less damaging" choice. I might change it though if needed. Note that you don't need to have max relationship to end up with a certain romance at end of the story.
As for search for Grace choice, yes I removed it and in practice now always shows in the main plot so it always happens since was causing plot-holes later if you never apologize to her. Hope it makes sense :)
