Same here, beat my opponent with more than 30 seconds and I still failed the contract...any H/W we all share?
My box is an Intel I5 6400K, 8 GB RAM, RX480 8GB, controller is the Xbone S, I'm also having a nice pint of Spaten Oktoberfestbier. (you can't be too precise... :P )
Here a Video of my Problem: https://www.youtube.com/watch?v=0h6K...ature=youtu.be
It always fails in the middle of the Track!
