cannot save track

[skypickle]

I recently started the ARGO campaign and am enjoying it. Howevewr, half way through a mission, real life interrupted my adventure. I thought I would end the mission, save the track file and come back to it later. However, when I replayed the track file, the helo didnt take off. I could see the controls indicator move but the bird was grounded. This only happens in this campaign- is it a bug ?
