XF 1.2 Always having 1 Selected Thread

So I'm having an issue where XF is telling me that I have 1 thread selected, even though I don't. I've been doing a lot of work on the forum - deleting forum nodes and adding them. So I believe that the thread that was selected was probably deleted along with the forum node it was in, because I cannot find any threads (only 5 in total, atm) that are selected. Is this a bug or is there someway I can fix this?
