I got error 10102 this morning, after I logged out safely in Gridania last night.

I mean, I'm not entirely happy about this, but my jimmies aren't exactly rustled. I love the game so far, so as a fellow lover of the game, it sucks not being able to enjoy it as much during early access. We'll get it back eventually though.

Also, the JP servers do probably have more problems than we know of, since most of us are on NA/EU most of the time. And I have seen them go down before.
