I get invited to this mission quite often and am more than happy to tag along to help get my levels up. One thing I have been noticing a LOT lately, is the mission failing due to the document being destroyed. I was just in a party of 4 and we attempted it 4 times in a row and we got this failure each time. How exactly did the document get destroyed?
I know that blowing up the car with the guy in it will destroy it, but this is happening before he even appears.
