The stickied Blizzard thread - How to Write a Good Bug Report - says this…
The information about how the Broken Crown works via emanation was added to the stickied Things That Are NOT Bugs thread in April 2021. Despite that, we continue to have threads misreporting the functionality as being bugged, which it isn’t. Indeed, there have been 33 threads misreporting it since the stickied thread was updated.
I suspect Nefertiri’s frustration got the better of him/her, as the Broken Crown and Stone Gauntlets are the two most frequently mis-reported things that are not bugs, despite there being stickies for people to consult before posting advising why they are not bugged.
