Threads hidden in Work In Progress forum

I posted an announcement thread earlier this morning, and for some reason it is hidden in the work in progress forum. The only way to access it is through direct link, which you can see here - Project Reverie - Sci/Fantasy Third-Person Action Game! - Work in Progress - Unreal Engine Forums

What is going on? This isn’t the first time something like this has happened. It’s pretty significant given we just announced today and no one can see it in one of the major forums. Assistance would be greatly appreciated.

It’s a rare vBulletin (forum software) bug that we haven’t figured out yet. I just posted on the thread and it’s made it appear in the forum section now.

Thank you for your help Stephen. =)
