Steps to reproduce:
- Create a forum
- Create several topics for that forum
- Vote some of them (not all) - if you want with different users, in order to have more votes per topic.
- Click on Votes link from the forum page and check if something changes.
- Click on Votes link from the Most Active Topics panel and check the reordering. (here, there is some kind of reordering, but not a proper one)
