I have been seeing this question bumped to the top of the active list in Meta, showing in the list as having been modified by Community♦. However, when I look into it, I see no changes were made to the question itself, any of the answers, or any of the comments.
I haven't paid too much attention, but I sort of recall seeing the same on other questions in the past as well (this one I think), but I'm not sure of which questions get it or how often.
So, why does this keep bumping? Is this a bug or is it actually something happening behind the scenes that I just have the privs to see?
