tdx-util -R.  See the man page for the right flags and arguments.

It shouldn't have done this -- the only thing I can think of is that maybe
those articles aren't present in your overview database.  tdx-util will
put them back into your overview database, so hopefully that will address
the problem.  If they are removed again, maybe that means they're also not
in history?

So nothing was expired out of overview that night.
