• Go to a world like https://thirdroom.io/world/#uk-city:thirdroom.io
• Realise that you're in the wrong place, and change the URL in the browser to be https://thirdroom.io/world/#uk-city-1:thirdroom.io, and hit return
• Get prompted to join a world; click join
• Discover that you're back in #uk-city somehow rather than #uk-city-1
