Recently several trains have been shown as non reservable in the data but have then changed to become reservable.
This has happened to Virgin Trains and GWR for definite, and maybe others.
Here is an example showing an Advance from Plymouth to Doncaster with no reservation between Plymouth and Paddington:

The 1500 Plymouth to Paddington is now shown as reservable in the data for this date (25 May), but anyone who had purchased such a ticket a few days ago, without a reservation for the first train, would probably not be happy if they end up on a busy train with no reservation.
Furthermore, the Guard may expect to see a reservation and the lack of one may cause confusion.
Has anyone here been affected by this?
This thread is more to raise awareness of this issue than anything else, and so that anyone who is affected can learn the reason for it.
