Been having standard duty quest problems all morning, mainly in solo quests, can participate in duty finder fine.

Gotten error 90000 (which was apparently fixed) twice now but recovered form it.

Recently I crashed out while in a loading screen, and now can't get back in.
My game says there are no NA/EU realms, can't form a connection with them, but can connect fine to JP.
My wife is playing right next to me, on a much worse PC than mine, and is in the supposedly "non existent" NA worlds as I watch unable to locate my own.

Unsure if this is related to maintenance, 90000, the duty bugs or some other reason.
