Unexpected behavior onload and on-save

The onload behavior is corrected by the patch. The patch tests for when the loading node has access to a relevant tagging vocabulary. If it does not, then this module should do nothing. On-save, the module appears to wipe nodes. While that should be corrected, the patch simply disables any action on save at all. That may not be the ideal solution (as comments mention), but it does stop the dangerous buggy behavior.
