What it says on the tin.
If I now quote this message, and click on my profile name in the quote, it links back to community.ingress.com rather than to my profile.
I don't think quotes are meant to work that way. I could be wrong but usually the first quote isn't meant to hyperlink because if you click on the comment you can see what it says. The second quote after that (quoting a comment that quoted a comment), will have a hyper link that takes you all the way back to the first comment in the conversation. Every quote after that will have the quoted comment and the previous comment hyperlinked to follow the conversation.
On every normal post, clicking the time is a permalink to the post itself, clicking the name is a link to profile.
Both of those are broken in a quote, and they point at the homepage.
It's an issue with how the quote is rendered as an expanded link.
