Editing Posts Bumps Them Back up The 'Latest' List

Editing posts sometimes bumps them back up the ‘Latest Posts’ list, same as a new post in the topic would.

Doesn`t always seem to happen for some reason.

something to change/fix?


Seems to happen if you edit the latest post. So if you edit the OP and there are other posts after, you get no bump, but if you edit the last post, bump occurs.
