I will try that, but I have been exiting the group and ^U SPC to
re-enter and display all, and when a message has gone missing, I have
not even once been able to get gnus to show it.  I have exited and
restarted gnus, and done "g".

Are you saying that "g" in the summary does not allow viewing a missing
article, but M-g will?

To me, the problem is that these message are somehow invisible, even
after multiple attempts to fetch/display them.
