title: Drupal Nodes shows 404 when it exists
body: <p>Some nodes are showing a 404 status when they exist in the database. You also get a 404 if you type in the url to edit that node in the admin page.</p>
  
  <p>These nodes are being created in an automated fashion in the database, from CSV files. What I'd like to ask is which db fields would trigger a 404 on a node?</p>
  
  <p>I have checked the url_alias table, and the nodes have valid entries. ie: If I enter example.com/node/512682 in the URL, it will do a redirect to the SEF url, but that would show a 404</p>
