An error message "30" appeared on the display at the gate, at Kings

...which, at the time, they thought it did.

At Clapham Common Station, I was told by a lady there that I *had* to
renew my card there and then, as the card would never work anywhere
else.

...which, by then, they'd realised was the case. I'm not sure what the
"code 30" issue is, but it does mean that an unspecified number of
unfortunate types like yourself need a new physical Oyster card.

I very much doubt that this information was clarified between me
touching in at Kings Cross at around 2230hrs, and getting off at
Clapham Common.

True - in which case the person at KX was at fault, there were posters
up at Whitechapel by 1900 saying that anyone whose card came up with a
Code 30 would need a new one.

To add insult to injury, my replacement card now *apparently* offers
fewer benefits than the original. My original card was an Annual Gold
Card issued by South West Trains at Wimbledon Station. I was able to
join their Gold Service and obtain Network Card discounts as well as
additional benefits from South West Trains. Today I was told that I am
no longer a member of their Gold Service, my ticket is NOT valid as a
Network Card, I am no longer entitled to Network Card discounts and
that if I want my original ticket restored, I have to get it replaced
AGAIN, by South West Trains - at a charge! Is this really correct?

You've presumably got the Gold Card Record Card issued by SWT at the
same time as they issued your original Oyster season? If so, then
you're fine - it's the record card that's required to demonstrate Gold
Card eligibility, not the Oyster.

No, LUL, despite your claim of being vague about National Rail did say
that they had to keep the original record card, and that the new one
would be fine, despite my doubts.

Hmm. In that situation I wouldn't have handed the record card over in
a million years. However, the woman was still wrong: LUL-issued annual
Travelcards are also valid as Gold Cards on National Rail. At
absolutely worst, you've lost the SWT-specific benefits.

More insult, more injury - I discovered that I did not have to have my
card replaced in the first place, and that I could have waited till
today to do it in my own time, rather than standing at Clapham Common
Station at 1115PM!

Well, clearly, as long as you can get out of the system - did you ask
the staff at Clapham to let you through last night and they
refused...?

Because I had another bus journey to make, so when she said I couldn't
use the card again, I, for some reason, believed her.
Then on the bus the driver told everyone not to bother swiping in as
Oyster wasn't working.

So she was right that you couldn't use the card again.
