Hello Sudz,
Went over mission file segments and used fill to the end, then calculate buttons. Saved file and exited to run it in game to test. Mission hung at same point. closed AH, opened editor and made some speed and altitude changes. Used the fill to end and calculate buttons through to run out, clicked the file tab and clicked save option. Closed mission file and editor, ran mission in game and found no changes of speed or altitude, and messages in text buffer were listing original course settings. It again hung at warp point. I checked the file and changes were saved to mission, I'm wondering where I made a mistake. I had also used build res library selection, would that have any influence on file?
