I just upgraded the forum to vBulletin 4.1.12, which fixes a variety of bugs and also includes integration with Forum Runner (which I haven't set up yet--are folks interested in this?).
You can read more about the release here: https://www.vbulletin.com/forum/entr...ulletin-4-1-12
As usual, please let me know if you run into bugs or unusual behavior.
