In the mission "End of Chapter' I reached the part where 4 bikes run. I'm really not good at diving and shooting. By the time I killed the first biker in north Alderney the other bikers were somewhere around the the Booth Tunnel. I went to the last known location and there are no bikers and no red icon for them on my map or radar but the mission won't end.
I did stop after the first biker for health and armor. When I stopped I got a message that Brian's crew was getting away but after I got back on my bike and resumed the chase they just disappeared without a message that they had escaped or that the mission was over. I called Jim but got his voice mail.
I seem to be in a state where I don't attract the cops. I shot a pigeon at the toll gate without attracting cops but I did get one star for not paying toll. My safe house isn't on the map nor is Elizabeth, the gang wars or the race.
Is there any way to complete the mission without restarting?
