There seems to be an issue with people quitting straight from the game.
They will given a message stating they will be left logged in when they quit the game.
You can tell who is logged out if you look at the guild roster their level will not be showing.
In one guild there was 10 people logged off but still online and in another 13.
I only noticed this because I was on discord with somebody who had logged off over 90 minutes ago but was still showing as logged in.
Live a little love a lot send all your gold to this Imperials pot.
