Since you can already get all your companions back through the terminal, I'm not really sure what the problem is.
As far as romances they seem to have broken them at some point and I'm not sure if they even know where to start to fix them. The game doesn't seem recognize the romances you chose in the past and assigns random ones to you for the story.
The best I think they could do a this point is to make sure all new characters have working romances.
