[Logic_]

Try creating a vehicle under OnGameModeInit, call a timer and destroy it (after 100ms would be fine), and then you may try loading the vehicles using your function.

You should use printf instead of print if you need to show (a) value in it.

PHP код:

printf(" %i vehicles have been loaded!\n", vCount); 


You may as well, try printing the vehicle position while loading it, use printf here.
