Given that we can now successfully compile the game from the source code it's time to fix bugs. I've heard complaints about random crashes that persist when loading a save file. If you share the save file with me I can attempt to find and fix the crash.

Hi Armada651,

I'm experiencing trouble with airline tycoon as well, and I'm looking for a solution but cannot find it... One of the problems is that after a while of playing, flight premiums aren't paid anymore so it's not possible to make money anymore. Do you still want to look into save files to check if you can fix any issues? Because this issue makes the game nearly unplayable...
