Unable to Join Challenge / Already in Chamber
Today, I started a fortress challenge and received the error message "Unable to Join Challenge". When I tried to start the challenge again, I received the message "You are already in this chamber" (or similar wording).
This repeated twice. The thurd time, I was ready to screengrab it for you and it let me in!
