Condition:
Site navigation disappears for Authenticated users for one Site section only. The site section is a link which displays articles based on taxonomy. Specifically taxonomy/term/14+15.
When a user is not logged in (anonymous) they see this (the correct condition)

When the use logs in (authenticated) they see this: The Taxonomy access is correct (headers at top read Guest and Registered content) but the navigation is missing (incorrect condition) that has recently appeared.

I'm using Taxonomy_Access to control which content appears based on Anonymous vs. Authenticated access. That configuration was working correctly; the sidebar navigation always appeared
Now, clearly, I must have changed something but what specifically I can't seem to isolate. I'm in the process of turning every module on/off to see where the conflict lies.
Turning off Just Taxonomy.Module, I see this which makes sense. It's the error page since the Learning Center link (taxonomy/term/14+15) clearly isn't being produced.

With Taxonomy.Module ON and Taxonomy_Access.module OFF, I see this: Navigation disappears.

This leads me to believe it's a problem with the Taxonomy.module itself.
I replaced the Taxonomy.Module with a clean one downloaded as part of the Drupal 4.6.4 install package. In repeating the tests noted above, the results are the same.
