Whether ARROW encounters an error

I booked a ticket once, overslept and missed the train (Saver fare, so no value after departure), so I bought a walk-up ticket for a later train. The points never posted for the later train (but somehow credited me on the return) because ARROW hiccuped and thought that I was trying to credit three trips (missed train, outbound, return) on the same route in one day (limit was two, under the old rules).
