I made a thread asking about this a few weeks back. It's related to 4.86. What I ended up doing was docking my junker ships at Beaumont and shooting Xenos to make bunters non-hostile. It sucks though because it fit well with the rp of my character that bunters were after him for his heinous out-of-house-space deeds, but this resulting in Liberty Dreads shooting at me when bunters show is uncool. I can't remember exactly, but someone in the thread I made said something about bunters and house authorities having formed stronger bonds. I'll see if I can dig it up.
