In the method downloadVehiclesRouteC, we send a request to Syncromatics API for arrival prediction by vehicle. The response contains pattern name for the given vehicle and this helps us distinguish route C's vehicles from MSC Express' vehicles. However, the response is sometimes empty and causes the following bug:
