Hi, thanks for the report! Could you please go to Theme settings for your AI site: https://npub.pro/design?siteId=naddr1qq88xarvxyunswp68yukzwf3v5pzp2x32cxk5era2qtfj9njgmer0vm0ky3l3ytglks3m36r2vl7c7sgqvzqqqrhxq6qyrpn&themeId=naddr1qqzx2er8v5pzqz82megd75w6ffp0thqytc6mxuvs9crdd2q9y9d7c0tjm358ejcyqvzqqqrhxg7zn273
Go to Theme tab there, switch the "Show related posts" checkbox on and off, and then save it. It's an old bug that should have been fixed - the event that was formed the last time you edited the site theme (a boolean was written to event tags instead of a string), but some relays still accepted it - so no error was shown to you, but now some client code accepts the event, some rejects it, etc. After you re-edit and save it things should get better and site will start updating, hopefully. Please let me know when you do that. Thanks!
