Shortly after the Prydwyn came to the Commonwealth, a Brotherhood Lancer-Initiate showed up at my Starlight Drive in settlement. He didn't do anything except stand there. As it was my first playthrough, I didn't think anything of it. I just came back to that settlement for the first time since destroying the Brotherhood, and not only is he still there, he can't be killed. He is marked as hostile, so all my settlers are attacking him, but bullets, lasers, and melee weapons fly through him as if he wasn't there. He is still solid enough to where i can push him, but otherwise he still just stands there. I would try to slowly push him out, but he seems to like his spot and keeps running back to it.

Is there anyway to get rid of him? Or will i just have to avoid Starlight from now on?
