Task setup time is not applied to the first task at the same place
Task setup time is not applied to the first task at the same place if a vehicle starts at the same location where tasks start (in a case when vehicle.start coordinates are the same as shippment_step.location or job.location coordinates). version v1.12.0
It's not a bug, it's a feature. ;-)
The docs state that the total "action time" for a task is [...] service only if performing a new task at the previous vehicle location. This applies to the situation where the previous vehicle location is the vehicle start, so no setup time applied.
If you want to account for some loading time, you can push the vehicle time window start a bit later.
If you want to use setup time for loading at driver start location (i.e. depot), and are using location_index for distance matrix, you can simply provide different values for start_index (driver) and location_index (job/shipment) even if coordinates are actually the same -> the locations will have 0 cost between them so nothing changes in the route, and this will actually make Vroom apply setup time at start location.
