Thank you for your prompt response. It's really rewarding to actually get information back from game developers AND SO RARE
You might have missed a mission trigger somewhere. The instructions "go there, do that" have to be followed precisely. I did not have the time to add fail triggers for every eventuality. That alone would be many months of development.
I can see how trying to code for each eventuality would be quite complex, not knowing the mechanics of the framework you are working within, I didn't give this any thought. Sorry.
Editing cruise speeds also is not the best idea since some of the following missions have internal timers. It would cause problems if you reach stuff too soon.
I wonder if it would be possible to list any of the internal timed missions? I don't have much time for gaming and tend to dip in and out, sometimes for as little as 30 mins. If I spend most of that flying at snail pace cruise speed it's enough to make me think of playing something else the next time I fire up the PC. Sorry to be blunt but that is the reality of the situation.
