You click on the thread link as you did before but now you're brought to the very first post of the thread, this is counter-intuitive IMO, I fully expect to be taken to the last post in the thread if I've read everything.
Can I ask that you consider modifying this behaviour.
Try it for yourself, check out this link, go to the very last page. http://xenforo.com/community/threads/redirection-scripts-for-invision-power-board-3-1-x.14652/
No navigate to the containing forum http://xenforo.com/community/forums/add-on-releases.32/
Click the thread title again, where do you land?
