So I have Veronica as my Follower, I've completed all her quests up until we get ambushed outside of the brotherhood hq. I have never had this bug happen with any other follower so Idk if it's just her or what. But ever since the quests finished, after awhile of walking she gets stuck running in place. When I walk up to her, she's a ghost.. Meaning I can run through her and can no longer interact with her. It's fixed by reloading, she goes back to normal. But again after a few minutes, even seconds of walking, she goes back to ghost mode.. This can be quite frustrating, especially when I get randomly ambushed or something.. If anyone else has had this problem and knows a fix, please let me know.
