There is a Brotherhood lancer stuck on top of the barn at co-op. I killed the BoS so he’s hostile. He’s also invincible. Every time I visit the settlement the settlers open fire on him and he just stands there, mighty, as 20 people and various turrets shoot at him indefinitely. It’s annoying because I can’t craft anything or trade with the settlers and it makes it difficult to build up the settlement.
I have to leave for a day so for them to forget he’s up there.I’m sure there’s a console command or something I can use to get rid of him, but I’ve gotten fond of him so I just let him stay.
