Opening RecentChanges page now shows the edits from the last 0 days by default (ie. "in last 0 | 1 | 3 | 7 | 14 | 30 days". Clicking on the usual 7 days, removes the 0 from the choices, but each time you reopen the RecentChanges it's back at 0. Is this intended? edit: here is an image http://www.imagebam.com/image/ef511a426690019

Also another bug that is since the Breakpoint Typography, which I also reported, but was told since it isn't happening on many wikis it won't be fixed anytime soon (or ever). So to spread the word:
 * If a wiki didn't had a custom background when the breakpoint typography update was made, adding a background now will create a bug in which the background won't move to ensure the same visual background image space for large and small screens. Usually when the breakpoint occurs, the content area increases, but so do the space located on the split, keeping exactly the same visual part of the left and right part of the background. And that makes it impossible for such wikis to have same look on different sized monitors. Image example of what I mean: http://www.imagebam.com/image/da45bb426687552 (on the top image is how it should looks; on the bottom part of the image, you can see how the breakpoint fails to move the background and the desired effect is lost as part of the background stays under the content area)

The wiki on which this is happening: http://shingeki-no-bahamut-genesis.wikia.com/wiki/Shingeki_no_Bahamut_Genesis_Wiki It's also happening on couple of more wikis, and like I said, it happen only on wikis that didn't used to have a background until recently. So if someone had started a wiki before the breakpoint update, and added a background recently, this will happen on it's wiki too.
