I could not reproduce, please update to the latest release and test this again, since 18.0.2 is heavily outdated 😉

[Wastl2IT]

I have the same issues on NC 19.0.1, nginx, php 7.2.24.
Also:
User A shares files with user B.
Any file ownership (doesn't matter if it is shared or not) moved from A to B.
=> every existing share now points from B to A (owner-field in sharing-table changes from B to A).

It doesn't matter, if the occ-command or the dialog in the browser (settings, share, transfer ownership) was used.

[juliusknorr]

Pull request for this issue is at #22116. Testing is very welcome

[GAS85]

Thats so bad.... All Shares between User A and User B are broken when User A transfer 1 even non shared folder to User B.
How it was:

How it looks like when 1 folder being transferred:

This is win!
