User cannot move shared file to shared folder

Steps to reproduce 1. User A shares folder FO (which is located at root) with User B 2. User A shares file FI (which is located at root) with User B 3. User B moves file FI to folder FO Expected behaviour File FI should be succesfully moved to folder FO, since the folder is also shared among both users. Actual behaviour In user's B view, it seems that everything worked fine. There is no warning, no error message, nothing. But when user B reloads the page, she sees that moving the file didn't work. In the other way round, if User B had uploaded a file directly into folder FO, and user A tried to move this file out of this folder, the file will disappear to User B, who uploaded the file, definitely, and User A will have this file in his root folder, not shared. This is the expected behaviour in this direction, but the other way round it's not working as expected. Server configuration Nexclout in branch master Operating system: Ubuntu 16.04 Web ser…
