Hi,
Recently I cleaned up a site that I run and deleted a user I had created just to test some things out (user/2). There were a few nodes in the database that were marked with uid 2. Logged in as user/1 I then found that the nodes marked as uid 2 were inaccessible - to logged-in users, anonymous users and anyone, regardless of any access rules I had created. Editing the affected nodes via PHPMyAdmin and setting the UID to 1 has restored access again.
This is on the latest 4.6.5.
Has anyone else found this?
Tim
