Thread:Extension talk:Lockdown/Extension doesn't work with 1.16.0/reply

Update: Now the extension works after doing this:
 * 1) Create a restricted namespace
 * 2) Create an article in that namespace with a user who has permission to do that
 * 3) Log-out (until now, nothing had changed; I'm still able to access sysop special pages and change user rights as an anonymous)
 * 4) Search for the article, created in step two
 * 5) Click on the result (there shouldn't be a result!)
 * 6) Now you get a restriction failure
 * 7) From now on, the extension works as expected

The buggy behaviour, described above appeared today's morning out of nowhere. I used the extension for several weeks and saw it today for the first time. Any idea about that?
