Maybe you're seeing cache then? Dunno.
Looking on that njump link, I am hooked up with band & nowhere, so that's probably it
I can also see the quote post on Amethyst, but if I tap on the original note or search for the note ID, it can't be found.
How it displays in the feed: https://file.nostrmedia.com/p/4eb88310d6b4ed95c6d66a395b3d3cf559b85faec8f7691dafd405a92e055d6d/50aa9744ef92ee15919ebb64bd94df599e02bb47ebd6534797d1c11c4d224e7b.png How it displays when searching for the note ID or tapping on the original note: https://file.nostrmedia.com/p/4eb88310d6b4ed95c6d66a395b3d3cf559b85faec8f7691dafd405a92e055d6d/07494f4238d84e90127c2de142e91d6c057a2a9b2f6bca43d1f8407f9f154ab6.png
That's really odd. And I'm confused.
If I recall correctly a user can essentially "undelete" a note if they overwrite it with the exact content. My initial thought is that maybe the repost has done this in some way in order to recall the quote post. I'm sure someone will chime in with more details.
