As of August 23rd, I am having the same issue. It happened as I was teleporting to Valkurm Dunes via Horst in Port Jeuno. The character select screens shows that I am in Valkurm however if i attempt to log in, FFXI and POL both crash. Logging into my mule character works just fine.

I'm not sure if this is a related issue as well but, about an hour or so earlier, I was attempting to outpost warp to Beaucedine Glacier via Jeanvirgaud in Northern San d'Oria. I'm used to certain NPCs not loading from time to time. Normally if I run far enough away and come back, zone and zone back in or log out then log back in the issue normally fixes itself. This time it didn't however.

If someone could help me with this I would be eternally grateful.
