I've played it,but i can't see the full problem coz i couldn't pass the mission.When i 'm going up to the parking,then written is 'Mission Failed!'.
Anyway i could see your problem. It's because you've used much rute points. You can't more than 369 or it'll crash or it won't work.
I saw in the mission,you've used rute points to move limo and another one car from dragon casino to the parking. Distance is long and two cars! So you spent rute points.
1.You can't use more than 369 points.
2.When you making mission,sometimes check it out how that will looks like,cause if you don't do that. When you start play mission no-tested.
If you see the mistake in making mission,small chances are that you can fix it.
