Hmm, nothing in this case - my journey was not unresolved, since the
machines were off on entry, and the SAs were nice on exit. :-)
I thought you said you couldn't get out at South Woodford. Was this
because the Oyster wouldn't open the gate or because you didn't try
because you realised that not validating at Leyton would cause problems?
I tried and it didn't let me out.
However, I'm still struggling with understanding for which reason it
chose to do so!
i.e. because there was zero prepay (should have let me out with a
negative balance?) or because there was no recorded entry (should have
done - er no idea) or some other reason.
My guess is that the gates at South Woodford didn't let you out because
there was no recorded entry point given that you had travelled beyond
your zonal availability. The system needs to know where you entered to
calculate any pre-pay deduction as you could have entered at Zone 6 at
Epping or equally Zone 5 in West London.
