The error message "WARNING: Your character does not appear to have any pets." Comes up when trying to update via the armoury. I'm in the UK, so am already running Mists (Hello from the land of tomorrow!)
I'm not sure whether this is a bug due to the site running on a US, non-mists system thingy, or whether it's just me. Can some more EU players try updating via Armoury, or a US player once Mists hits over there?
