I seem to have reached an impasse now... I'm backing the Railroad primarily, but in the process of ingratiating myself with the Institute, I've pushed their goals further than I really intended to.
So now, I've followed the Railroad tasks to the point where I've been told "keep working with Father, so they don't get suspicious"... but Father doesn't respond to my attempts at conversation. I'm pretty sure the Institute is waiting for me to take the next step after aquiring the Berillium Agitator, but from what I've read, the next step will be a "point of no return" that will require me to forsake the Railroad... how do I proceed now???
