I have no idea how to change it back to normal. It has the topic post, but then everything else is in a list after that called "posts in this topic".

Click thread options and select "standard" under "Display modes"

It's happened to me before and I seem to be one of the few members who actually knows this!

Where the hell is options.

Under the reply and new topic button.
