Forum:Movement of a page does not show up on logs?

On an other wiki a Page seems to have been moved twice (to a new lemma and back) as it vanished from the New Pages Log but no evidence of the first movement seems to retain in the movement log or history of the page. Under what circumstances this can happen? To my knowledge an undo on a movement is not possible. T-Stripe (talk) 11:34, November 15, 2012 (UTC)

 * the Page in question is http://heromux.wikia.com/wiki/GearBox - Please do not edit anything on the page as now it is in the corect place, but it gave me trouble with the admins there as it was not on the corect place for some reason. T-Stripe (talk) 21:12, November 15, 2012 (UTC)
 * I see what you mean about the first move not appearing in the history, thanks. I can't seem to replicate this myself. -452  21:48, November 15, 2012 (UTC)
