For me when I try to delete a post it says ‘(post deleted by author)’ but then instantly reappears as the message as if I just restored it but the delete button is a restore button.
I can report simularly to above. This was tested in #bulletin-board
For threads, it shows the visual deleted for leaders (red post) with the ability to delete. There is an option to reopen. There is no orange edit note for such actions
For replies, simular to above however I visually saw that it did show the orange edit indicator as it should but it near immediately removed itself.
Deleting moderation actions in a PM does not delete immediately.
Site note of the timer is that now every edit is marked as an orange change and not after 5 minutes
