I have two users, "Admin" and "Youssefk", both are following each other. So "Youssefk" created a new thread in a forum and then "Admin" moved it to another forum. Now in the admin's news feed, it shows that "Youssefk" has created a new thread, but when clicking on it, it just shows and error page saying: "The requested thread could not be found." that's because the link to the thread is not updated.
I'm still learning web development so I don't have enough skills to fix this, I hope it gets fixed soon
