Lost significant work after Save As (v5.4)

Looks like I have run into a similar issue to this one

Lost significant amount of nodes after “save as” used (v5.2) - KNIME Analytics Platform - KNIME Community Forum

I have been using Save As on my local machine to create save points in a model I am building.

Normally I close the application and leave the model open but this time I did not and when I restarted it, it had reverted to a version from 9 days ago.

The files have more current dates and the SVG file reflects the most recent save point, but I cant seem to bring back the latest version. In fact, all of my save points reflect the 9-day-ago point.

I think that there was an update around that time which may or may not be related.

Yes I know I could use github or the server but… I should also be able to open a file that I just saved.

Any suggestions on how to recover or at least prevent in the future?
