All right, let me head this by saying I sided with the Minutemen and saw no reason to destroy the RR, as they're not as much of a threat to the MM as the Institute or the BoS.

That said, I did some radiant stuff for the Railroad post-ending and post-BoS destruction, and they keep talking about Glory as if she's dead.

But I see her walking around HQ. However, I can't interact with her (or, well, I can but she doesn't speak). Does she die in the RR questline? I'm assuming so, and my game just can't seem to register that I didn't do their ending, or the quest dialogue is just locked in to be that way.

She dies when the Brotherhood attacks the Railroad yeah. That seems to me to be an oversight, one I'm surprised they didn't catch.

Bummer. Oh well, it's not a huge problem.

Still surprised they let it slip, as you said. Here's hoping they fix it in a patch.

Edit: I even checked the chalkboard, and her name isn't crossed out.

That's probably Glory 2.

She's of the same model and make as the original.

JK.

We have the technology.

Hey, same here! Glad I'm not the only one having this issue. Hopefully it gets patched.

I sided with the BoS last time and of course they are all dead (except P.A.M., whom I have no idea what else is to happen with it other than is just standing there in the blimp now being studied).

I don't understand what you are saying though. I'm siding with the MM on this current run and really can't understand why the MM would kill off the RR. Not sure what threat they were to each other. I mean they both don't like the BoS and Institute, but can't understand why they can't get along together.

Huh? That's exactly what I said in the OP
