During the quest Last Voyage of the U.S.S. Constitution if you have Cait as a companion, when you confront the scavengers and are given the choice to either side with the robots or side with the scavengers, Cait has dialogue responses that make it clear that she does not like the decision to side with the robots and does like siding with the scavengers, as befits her character, however when you choose to side with the scavengers despite vocally agreeing with the choice Cait gives a dislike affinity change. Seems like an oversight as in most situations Cait is against helping people, particularly for free, however in this instance this is the option that promises monetary benefit alongside her given opinions on the situation.
