So the new update still does not fix the unkillable Brotherhood Vertibird pilot glitch? I have one of these guys hanging around Starlight Drive In and the glitch has ruined the settlement as all my settlers do is try to kill this invincible guy who just stands there.

I was hoping they were going to address the issue in this update, but I guess not.

What provoked your settlers to attack the pilot? I have one of those pilots hanging out at Kingsport Lighthouse. My settlers are non-hostile towards him. But if would be nice if the pilot could join my settlement.

I am aligned with the Institute, so perhaps my settlers recognize the fact that the Brotherhood is my enemy.

You can provoke him by bringing in a certain companion that flags you as temp enemy to BOS.

The way I was able to get rid of the ghost pilot was to summon a vertibird and fly somewhere. I am still friendly with BOS though atm.

Are you completely unable to summon a vertibird?

If you cannot (I've not aligned with Institute, and you can still summon the vertibird as Railroad or BOS).

The other way I was able to temporarily fix the problem was bury the npc ghost with geometry. Using the wooden floor element with the concrete block base, put enough of them over the npc, then build a wall around him (cause he may move out of it when you leave and return).
