So first I have to say these missions are utterly fantastic. I never, ever get bored playing these!

So I was playying a mission today, completed the objective, and called for helicopter extraction. The helo showed up a couple minutes later and landed. I ordered my squad to get in. At first they started moving towards it, then out of nowhere my player (Without my input) ordered them to disembark before they'd even made it. They replied "negative", then stopped, and wouldn't board the helicopter. This same thing happened each time I tried ordering them on board.

I read the other support discussion relating to this, does my squad have to be outside the AO completely before calling for extract? Or did something get weird?
