Twice now I have touched-out at Kings Cross St Pancras station on my
way to St Pancras International train station. On both occasions, the
"Exit" has not been recorded on my Oyster account, and I have been
overcharged.

I know I touched out, because I managed to get through the barriers,
so how come it didn't register?

Another OSI query?

Don't know. My Oyster journey was ending at Kings Cross tube. Onward
journey was via Rail with a traditional paper ticket.

I touched out of the Tube station on Oyster, but did not actually exit to
the outside world.
