thank you for not giving up.
I have no clue and skipping this feature.
I do not get it triggered. I even cloned your whole repo - but nothing on 2 separate test instances.
there needs to be something wrong with the file-hooks. because the user-deletion-hook is still working without issues. Don´t know if its a combination of enabled apps or something. But when I am having the issue, others could also have it.
As this does not seem to be something stable to rely on, I will not implement it.
one question: what is “version 13” in your screenshot?
