A few times lately someone has replied to me and I click on their comment in my inbox to reply back. It takes me to the thread, but only shows a parent or sibling comment, not the reply that was in the inbox. But if I go back to the inbox and click on their profile, I see the comment in their history.

Most recently, this happened to a comment from Azzy@beehaw.org. They sent me a reply telling me about a containers plugin in Firefox and I just want to reply back thanking them for the tip.

Is this a real bug, or is it an artifact of how some instances are not federated with others?

Edit: Link doesn’t seem to lead to their account. Am I linking it wrong?
