Somehow a developer has managed to royally screw up a site collection. The site collection has the Publishing Feature enabled and it's working fine. A botched migration from 2007 to 2010 has caused some issues. Now the "Site Collection Documents" and "Site Collection Images" show up twice when you go to the View All Site Content page. In addition, clicking on the lists yields an error as it can't seem to find the list.
The fun part is opening up SharePoint Designer. You can bring up the lists and they actually have a GUID. Trying to delete the lists in SPD yields an error message "Could not save changes. This list cannot be deleted" (regardless of what account I use). And I even tried using a PowerShell command to delete the list. I get the same error, "Cannot delete list".
I suspect the list doesn't exist but there's still a record of it in the database. The only way I can think of fixing this is to do a direct database edit, which I really want to avoid.
Looking for new suggestions or ideas.
