On mission 3, prior to 2.7 update I was able to refuel with the tanker and continue on with the mission as planned. Even AAR the second time. Unfortunately I never got to finish the mission as the whole area lost power as I was 20 miles out from Mother. Got around to playing the mission again finally post 2.7 update, however my wingman Nail 4-2 will connect with the tanker alongside me, but he will not disconnect from the tanker at all. I restarted the mission, same thing happened.
Also, some radio messages do not come through as before, or they will come through several seconds after Flip has replied.
