After upgrading to Mavericks all data kept in the iCloud drive (/Library/Mobile document) is invisible in the finder. Clicking on the map doesn't show any result.
However, accessing one of the files via the recent file options in Excel or Word is possible.
The missing files must be still there, the size of the map also indicates that the data is in it, but there is no way to retrieve the index. This means that only known files with the exact filename are accessible. Of course I don't know all the files by heart, so at the moment I'm not able to figure out the content.
Any help would be appreciated.
