About not being able to speak to Roberto.
This issue was brought up like a month ago, yet the problem still occurs.
I have the problem which many others have aswell, I'm stuck, I have to start over because I can't turn in the main quest, nothing happens when I press E.
My question now is, how far have you come, when is it worth trying to play the game again? Right now I wont try to start over, hoping it will work then have to do it all again.
