Parent path not known - TTerminal::CopyToParallel

Copying a large folder hierarchy results in this error happening. This is a regression, since it does not happen with the stable version.

I was copying my Kodi library from my thumb drive to an 8TB Seagate BackupPlus plugged into a Raspberry Pi3 Second-Generation quad core models (Model B 1024MB) ARM Build running OpenElec 8.0.4. I dragged the folder into the queue after going to /var/media/(external drive) and just let it copy like I always do. I saw that the WinSCP icon on my taskbar was lit up and expected to see a message saying that the upload was delayed, but instead I got the below. Clicking the OKs obviously closes the error messages, but it also either completes the transfer, or the transfer was completed already and just had an error at the end, because it says completed then the queue empties.

I tried it three times in total. The final time I deleted the folder from the remote, disconnected the session, closed WinSCP, and started fresh with opening WinSCP and reconnecting. It still happened.

1. Connected harddrive to PC. Can browse and open contents on harddrive.
2. Connected to remote server using WinSCP
3. Navigated to desired upload (local PC) and download (remote server) locations
4. Upload file (>200MB). Upload fails. However, uplaod of smaller files (~ 10's MB) working.
NOTE: Accessed WinSCP after ~6 months. The upload of the files/harddrive worked then. Seems to be a recent issue.
