Hello everybody.

I've encountered something very troubling.
I've had a few locked nodes (basically nulls) holding some pieces of geometry in a hip file.
And now that I've opened the file after a while the nulls are still there but their content is zero.
Basically the nulls lost their locked content.
If this is a bug I think it's very serious.
I need the locked geometry as an example input geo for various stuff.
It is a bug or what?
Can I do something to bring back the geometry?

I think that is what the stash node is all about.

Go back to a version of your file where the NULL still contains the geometry and drop down a stash node after the NULL. Then lock that stash node and copy and paste it into the latest version of your scene. Discard the troublesome null in your current scene.

Yes, thank you, I know about the stash node, but (if I'm not wrong) this is a new node and the “null locking” was part of the workflow since forever, it was “delete history” Houdini style.
