The point contact of the ball might have aggravated a soft valve stem.
Take a close look at the others - might be a lot problem.

Yes, a lucky catch. I still had plenty of thread on the adjusters and
didn't notice that valve being excessively loose the last time I
adjusted the valves. But perhaps I didn't adjust them as often as I
should have. Still, I don't think I had to turn it in any more than
the others the last time I adjusted it and that couldn't have been too
long ago. I had swapped my dual carbs out for a single carb sometime a
few months before it died on me and I'm sure I adjusted the valves
then. I was driving all through the New York winter, 70 miles a day up
to 65 mph. Which explains the transaxle failure.
There are no caps between the adjusters and the valve stems. The flat
area of the ball contacts the stem directly.

Tried the link again, got through. Looks like the end of the valve
was not hardened correctly, and just got eroded away. A little
longer and the keepers would have nothing to keep them in place
except friction. A lucky catch!
I can't imagine that happening quickly. Did you notice that intake
valve's lash getting loose on every check and just reset it? That
adjuster would have run out of threads pretty soon.

Do you have the adjusters going direct onto valve stem? Or are
there caps between valve and the ball foot adjusters?
