You need to create new vehicle spawns. It is no longer possible to produce multiple vehicles from a single spawn point. Currently once a vehicle is spawned that spawn location will produce no more vehicles, until that type of vehicle is destroyed. The min and max vehicle spawns works a little differently now. For example if I have 10 different spawn points of "CAR A" but in the vehicles table the max limit is 5, then no more than 5 "CAR A" will be spawned in 5 different spawn points. If the limit is 5 but I only have 2 spawn points then only 2 "CAR A" will be spawned.
