Mission did not end when reaching extract location. otherwise a nice easy one, thanks

Mission did not end when reaching extract location.. Extract via helicopter? You cant get into it, to extract. I think all in all, it was pretty good. Nice job.

-Could do without enemy locations marked. Matter of fact, not much of a hunt if you know where your squad is already.
-Enough supplies at the beginning to feed a small army? Must be a hard mission?
-Way too many empty vehicles just lying around?
-BAM! "Must be an ambush"...Too bad I took out the ambush first..
-Too many supplies?
-Squad mates did not join party?
-Yet another supply crate (?) just in the middle of the road. 'Supply crate up ahead' right as I run it over?
-IED's here! I saw them all with my super vision. At night. In the pouring rain. It tells me to go left, but I go right...all clear.
-Yay! Roadblock! I'll just drive around it..
-Mission did not end when reaching extract location, helicopter did not take off?

I got the same message when I went up to the lighthouse right in the beginning

A message appeared, that I found my squad and I should quit the game as soon as I reached the ambush. Also, I would suggest to remove the ambush marker. It's not an ambush anymore if you know there one going to happen.
