I had the same issue, so I tried the older version and it now fails for any file over 2GB. I have the free disk space check set to false so I don't get any warnings, but the system just stops transferring data with a 2gb file in the .sync for each failed file transfer.
Moving back to the new version now also has exactly the same problem.
