I just downloaded the mission and started playing in SP.
The Waypoint to the tribute Team is in the middle of the small lake, just a minor thing I know ;)
The finished tasks are not marked as finished, I got the Waypoint to both objectives (Shilka & Officer) but the "Meet team..." task was not finished. During the fight to kill the officer, 2 of my men got wounded. Neither dragging nor healing was working. Again after clearing the area the task was not marked as finished.
I just wanted to give you feedback, let me know if I can help testing.
