Prior to restarting the client and having this issue I was unable to teleport using the Hyper Teleport Rock, and had tried to enter the CS from Ardentmill with no response, and I was unable to change channels as well. A Town Return scroll did work.
Edit: Apparently I still show as logged in to others.
Steps to reproduce:
Attempt to enter Cash Shop, when nothing happens restart client.
Be unable to select a server.
