I'm currently on The nuclear option, But instead of finding the tunnel going into the institute.. I fast traveled straight into it. Now I can't escape it.
I've got to the point where it gives me the option to go to the reactor, and talk to Preston.. But because they didn't travel with me, I can't do this
Hopefully i've not totally messed up, and there's a way around this?
I can't go back to an earlier save, because it's autosaved too many times in the same place.
