I just had YummyFTP do some really weird stuff while renaming files on a SFTP server... apparently it shifted the parts of the name I was trying to delete (and then some) simply "to the right". The result:
one file that was called "wertungsschema_dienstag-samstag.incl.php" is now called "wertungsschema_", has permissions "amstag.incl.php" insetad of -rw-r--r--, links -rw-r--r--, and Owner/group "1 / username".
The other file was called "wertungsschema_dienstag-samstag.incl. copy php"; it now has the charming name "0014/10001", has permissions of "ertungsschema_d/ à†", etc.
Of course, now I can't read, download or delete the files from within YummyFTP. Going back to 1.5.2 might not be a bad idea at this time...
