I just logged on and wanted to goto creative, but when I did /lobby It said "you are already connected to this server". I can no longer leave easy servile. I hope someone can help. Thank You Snow
Are you using Minecraft 1.8? You will get that message if you are trying to connect to a different server with the wrong version. Try reconnecting with Minecraft 1.11 or 1.12 (not 1.12.1) and then try to use /lobby again.
