A couple of weeks ago custom emoji set 'Nostr Purple' disappeared after the domain's SSL certificate where the files were hosted expired. The owner has not fixed this yet. I just republished them to my domain. If you used to use the 'Nostr Purple' custom emojis, you can now add them back under the new name 'Nostr Purple Republished'.
