#[4] might be able to help?
Discussion
I think #[3] summarized it well but there are lots of weird edge cases/race conditions with follow lists and relays.
There was also a client putting npubs in kind3 events instead of hex for a while which was causing client parsing issues and broke several user’s follow lists.
I know nostrgram.co used to have a way to view your kind 3 event changes and restore old ones. I know there are several others.
Thanks for the response. I’m trying out nostrgram 🤙
