I have twice tried to complete this mission. I can report the following:
1. Both times, my squad does not move. They will go prone and stand up if ordered to, but will not move. I havent tried the other workarounds, such as shooting and healing them.
2. In the first game, I captured all the towns but most of the 'capture ____' completion triggers did not activate, so I was still being told to capture these towns. I didnt want to try completing the rest of the objectives (eg. clear out the airport) since I suspected the mission would not complete with these objectives still showing as incomplete. So I restarted the mission.
3. The second time, I captured the first town but although the completion flashed on screen, I got none of the follow up 'Capture ______' objectives, so I assumed the mission was broken and quit. Again, as noted above, my squad would not move.
I agree that some udpate on the progress of the next patch would be welcome.
