Non updating mission objectives?

[KnightFandragon]

ahh, so you have to order all your guys back...soo if i order them all back early then it will activate it? I always wondered how it activates.....I thought there was some strange connection between me retreating and it activating....The Train mission finished for me at like 170% and i never did lose the front...even w/o editing I dont lose the front. THe key to winning that mission is keeping your T34 alive
