I was disconnected during an instance (Garuda story mode that I'd joined from mentor chat to help someone) and it took almost 10 minutes for the server to recognize that maybe I wasn't still logged in after all.

I tried exiting entirely from the launcher and re-authenticating, I tried switching characters, servers, and even switching data centers - nothing helped.

Is there some trick into forcing the lobby server to recognize that maaaaaybe a disconnected character isn't really logged in after all? Should I be waiting a longer time before attempting to re-authenticate?
