Well, actually the only thing I can think of is the "Active Topics" mod I installed in the ViewTopic page. It comes after the Quick Reply and before the footer. I bet that's the problem. I'll have to figure out how to pass the state around the ViewTopics file.
Edit: Yep. That's it. Okay.. so what variable needs to be passed to the footer to make it work again?
I'm assuming the Active Topics file I used has a conflicting "Locked/Open" variable with the same name. So when it loads a list of active topics it's using the "Locked/Open" state of the last topic in the list. So my question is what variable does the footer use to display whether it's opened or closed? Guess I'll go look.
