When you hover over the thread title and the first post has been edited by it's author, it shows you the text of the second post.

Example, make a thread. Put your mouse over the thread. It will show a Truncate of the thread title. Now, if I edit my original post, it will then show the Truncate of the second post in the thread when I hover over the thread title.

yea Nuk was aware of this I think, but didn't fix it... I'll see if we can poke at that sometime here...

Fixed.
