Character stuck in duty instance
Had massive lag spikes after entering a Wanderer's Palace instance. Decided to log off and reconnect to see if this solved the issue.
After restarting my client, I am no longer able to update NA / EU character list.
My friends reported me as still being logged on "in another world" (ie stuck in the duty finder instance).
I am able to log into a character on the JP regional servers without problems.
*EDIT*
It appears to have timed me out after 30 mins. Server list now shows. All is sorted.
