After upgrading from v4.4.4 to v4.5.1 I can't see symlinks anymore on one special ftp-server, on other servers they appear.
However when I type the known name of the symlink into the dialog I can reach the linked directory.

LOG from 4.4.4 - working

The output of MLSD does not contain symbolic link targets for type=OS.unix=slink. This issue has appeared becuase we now give MLSD preference over STAT if supported by the server (as per the FEAT reply) as of a9dc5c4.

You can disable the use of MLSD to workaround this issue.

This is a bug with Pure-FTPd and should be reported to them.
