Connection > GetDesignStatus > No Entry found for Object Id: N

There are a couple tags in our system that users cannot access using eB Nuclear desktop because they get the message "Connection > GetDesignStatus > No Entry found for Object Id: N" where N is the TAG_ID from the database.  The tag definitely exists as it is returned by the search and can be opened/viewed in director.  Has anyone seen this message and can you point me to what might be causing this?  While there are workarounds to see the tag it is inconvenient because engineering users don't generally have director.
