I've looked online but can't find it, just as a disclaimer, which is why I resort to posting here :)
I've done the train yard mission 2x now, but am unsure what the primary target exactly is. I exploded trains, Flak guns, etc. But twice I flew back, and couldn't get past the button that says "End Mission" in the debrief. I can click it, it seems to animate as if I had clicked it, but it does nothing. All other buttons work - but I lose my progress. So I have to restart once again, but this time, before flying across the channel back and forth, I'd love to know what I have to hit!
If anyone has done this and can tell me what it is I have to do, that would be great! Thanks in advance.
