The problem with dopolnitelnymi missions. (Mad Max)

Picked up an extra mission in the fortress of Brochures the woman with the child, and then the JIT - playing with fire, which was a glitch. I drove the truck Packed with explosives to the marker in the tunnel. There how to get there - through container, but can not pass (the wreckage of the grates and stick the spikes on the walls. Left the truck there and went ahead to seek the path. But, on the right there was another token Special war machine. I took the car and decided to return to the fortress (it a really special engine, like an airplane). But the map is missing the mission marker playing with fire, but still token war machine. I don't know what to do. And, in General, if you have one mission after another, the first marker is not stored. Now the same Brochures mission on the cheep steel for armor, also can not find. I would really appreciate your help!
