I'm trying to edit this specific list:
I can change the title fine, but when I swap #3 and #2 around it gives the saving popup, says list completed at the top and then loads this page!
When I return to the list, no changes have been saved. I've edited other lists since the site launch with no issues (except it still says I have 14 unread messages when I really don't).

 Maybe it's related to the "15978" at the end of the links.
