When a user favs one of my notices I got a mail from my instance notifying me so.
In such email, there's a link to the supposed profile URL that fav'd my notice. The error is that this profile URL is wrong, it uses my instance's domain insted of the other user's one. In my case, where I first noticed, the email said https://status.tenak.net/manuel/favorites instead of https://lamatriz.org/manuel/favorites
I'm using Git master branch, commit 61992dd9a254e94a5299f73a8d697d9e2c67cddd
