Error 10102?

[Kesia]

'nother Cactuar-ite checking in here. I actually came back from an AFK and found that I couldn't see chat from anyone else, just emotes.

My journal said it was empty, but my duty tracker was still active. I could only see a few other players. Anyone who was on a chocobo didn't draw on my screen; just their chocobo and no username or model.

I tried to zone to resolve it and got stuck on a black screen. Some friends said they could see my text but I couldn't see theirs. I've been on this error now -- and as of this specific sentence, NA/EU world down.

Figured I might as well post anyway with the rest of the context in case it helped at all.

Edit: I rebooted my client, now I'm in queue.

Edit 2: ...back to world full.
