There is suddenly a bug (in version 1.8.2) where the location name in the top right corner (Welcome to XYZ, delicious friend!) becomes clickable and leads to its correspondening wiki entry. Maybe this is even a feature, but if so it’s not working right: the displayed location name never changes from the one displayed when you first log in, no matter how much you then travel around London (or indeed, even the Hinterlands). It’s quite disorienting.
I’m using Opera only and haven’t tested any other browsers. I’ve deactivated the extension for now and everything’s back to normal. But since I’ve been making heavy use of the extension ever since it was first released (thank you so much for creating and maintaining it!), I hope it’s repaired soon
