I just reached the Minutemen ending, the last of the four I have played through. Only this one ended a bit differently than I expected.

A few game-hours ago I took a sudden action I had not been planning. Some character in the Railroad HQ would not get out of my way, so...before I knew it they were all dead. Except Deacon, who got it later. I thought about restarting from my flash point but decided to play it out.

So there I was in the fairly early game without the Railroad. The usual Minutemen ally for the ending. My character is now standing on top of Mass Fusion with Preston but there is no way to trigger With Our Powers Combined. Does that mean the BoS will leave me alone? Has anyone else done it this way?
