After completing 'Taken For Granted' quest and selecting the, 'Now is not the time option.' reloading that save will make the 'Let's talk about us" dialogue option disappear. This is frustrating if you're wanting to play your story a certain way. After playing around with it for a while to see if there was a workaround I found that even when loading to an earlier save and ignoring the mission and making a pledge, exiting a conversation with Randvi would now take 10-15 seconds which is an issue I also encountered after having completed the quest. At this point I have reloaded an earlier save and won't progress the story for fear of more bugs down the line and because I'd prefer to play the story through with my preferred narrative.
