1 pointI just wanted to follow up on the previous thread about the Faraday Cage and not being able to extract the car parts. I had to create a new thread as the original is now locked. I just wanted to say that I think my troubles with this was PEBCAK. Seems that the problem was that as extracting the parts from the cars causes suspicion I was being interrupted by a NPC before Arthur could complete it. It just really looked like he was doing it fully.
1 pointManually save inside the tunnels. Restart the console. That worked for me.
