@Cryssie the vandalism flood was pretty big. There was a new edit to a page every other second, and repeated ones to particular pages (like Connie, Grisha, and Marco) and we couldn't keep up, so the undo reversion editor wouldn't recognize an undo attempt if there was an intermediate one. There were too many intermediate ones for us to track down.
