sizeof(PizzaDeliveryLocation)

This will return the size of your define PIZZA_CHECKPOINTS and so it chooses a random number between 0 and 23. You only have 3 checkpoints added, so it will only work from 0 to 2.

Remove the define and PIZZA_CHECKPOINTS from the PizzaDeliveryLocation array or insert the exact amount of checkpoints.
