Thanks for the suggestions but something is still wrong. A quick scenario of balloon busting. I follow the tac lines to the balloon. I get there with my wingmen and signal attack. The message appears saying something like "arrived at task point". I shoot the balloon down and await the next waypoint on the tac display. It doesn't come. I fly around and around the balloon location until eventually some enemy arrive. I dogfight and at some point the message says "task failed". I have no idea how to complete this. If I select "end mission" I crash behind enemy lines. If I head towards the next waypoint the line just grows longer behind me. I even tried shooting up the balloons spotters but that is real hard and doesn't do anything. Is it a bug or am I missing something I am suppose to do. This is also how it happend when I had a balloon mission in the campaign.
