No, I was talking about the one shown below. This reply of yours appears attached to my post from gnusocials.net, but only as seen from my mastodon backup account that subscribes to my account on gnusocial.net. On gnusocials.net, your reply isn't displayed and, as @administrator said, not available.
@administrator refreshed my subscription-list (as this often resolves federation problems) but it looks like the issue persists.
