I too have this same problem , i run the game with latest patch and at start of the mission my team would not respond so i ran the mission through the editor then resaved it , placed it back into the campaign and the ai has worked fine ever since . I finally got all the objectives complete and after fixing the AI problem i quite enjoyed the mission but ... even though all the objectives have been met the game will still not advance the campaign i very much hope BIS will fix this sometime soon .
