I'm at the point in the game where I either need to commit to the Brotherhood and go kill the Railroad or keep working with the Railroad/Institute and make enemies with the Brotherhood but I'm stuck because two NPCs are broken and invincible.

1) If I ally with the Brotherhood and go to kill the railroad I can't kill Deacon.

2) If I make the Brotherhood an enemy I have some random Brotherhood Lancer stuck in my main settlement. Since they become an enemy my settlers and followers at my main settlement spend the next eternity shooting at the Brotherhood Lancer which is not what I want in a settlement (Too loud and no one's doing their jobs while trying to attack him)

In both instances (Deacon or the Brotherhood Lancer) I can not kill the NPC that needs to die. They are not targetable in VATS. I can X to interact/talk with the Lancer before he becomes hostile, but I can't direct him anywhere using my settlement controls. Simply isn't targetable with X during that mode. I've done everything including removing all floors below him and trying to body block him away. He always just teleports back up to the same spot and gets stuck there.

I don't know how to continue with this. The only other save I have far enough back before these bugs started is like 10-15 levels behind at the start of building the teleport before I picked any factions (Saved that so I could re-do different faction quests) but I don't want to reload that one because then I lose my entire main settlement which took days to get just right.

Not really expecting any ideas or fixes, just wanted to make sure it gets reported.
