Odd one last night. I walked from the Town Center to Station Park and ended up in a condition where I was getting the talk messages from the Park but nothing else. I was seeing the previous room, users, etc, but clicking on any of them generated ‘not found’ errors.
When trying to refine the console log to see what was related to the issue, I lost the log, so I don’t have that. What I suspect is that there was a network blip at a very inopportune moment.
