The “Commissar Is a Troll” thread. Same as what acsenray said in his thread that was closed, but it’s still happening to me. If I click on the thread itself, I get in, but if I click on the “Go to First Unread Post” button, I get the “Access Denied” page. It’s only with that button. But even if I have gone into the thread by clicking on the title or a page number, the button indicating unread posts remains lit up.
There’s some sort of glitch with that thread.
