Its a dumb bug from wikia. Wikia counts edits in the filespace as edits that should appear on the wiki activity page. Wikia is programmed to not show them on the activity feed since they can be quite spammy, but it still registers them. So when you do hundreds of edits on the filespace within a few minutes, the edits that are actually visible on the activity get pushed down until only the invisible edits remain. At least that's what I think.
