Catkin_ws removed from Opencv for robotics course

Two students that are following the course Opencv for robotics have lost their catkin_ws after disconnecting.
Is it a known problem ?
And is it possible to retrieve a backup of their work ?
Thanks a lot.

Hi Sebastien,

Apologies for any inconvenience.

Yes, it’s a known issue:

  1. It could be that their files had not been downloaded or the download failed.
  2. It could be that the last save was not successful.

Please ask the students to post messages here with their own accounts so we could check for them. Thanks in advance.
