Anyone experiencing the same issue/bug/error and have anyone solved this problem?
Please help me, I would really like a full bobblehead collection and I'm only missing the charisma bobblehead.
Best regards

I just recently finished the cabot house quest line with no issues. Are you patched to v1.3 though? I could sit down on the couch and communicate normally and just kept completing the dialogue options given by jack. After the dialogue he will walk away upstairs while asking you to retrieve his item and the quest will update. Try reloading a previous save.
