A fairly troublesome bug here: If an end user has the permissions of author/publisher and they go into the page settings for a page at the root level of the site they do NOT see "root" under the parent page drop-down. They instead ONLY see "Home" and not root which is where the page should be. The page appears to the user under home as well (incorrectly). Now, if the user then saves the page they then mess up their main navigation because the page moves from root to home.
Hope this makes sense. I just had a client completely rearrange their site on accident because they were trying to edit some pages and it switched them from root to home without their knowledge.
Thanks!!
