Getting a might frustrated, have a quest to return to mayor Kessler at Bunker Hill and trying to persuade her to join the Minutemen. The trouble being is she's walking around, starts the quest return dialogue when I'm within a certain distance, and as conversation options come up to reply or persuade her.... she starts walking away. Even if she's sat down when I start the conversation, she will stand up in the middle of the "cinematic" part of the conversation and walk away. Which ends the conversation before you can actually make any replies, and then won't let you start the frikkin thing up again.
