Presumably, given that under the incoming system (from November)
unresolved journeys cannot be resolved at ticket offices, this text
will be removed, and possibly replaced with some other explaination.

The warning notice now tells the user to phone the Oyster helpline to
resolve the journey (and has done for the past, umm, year or so?).
