Was running around the city in Rivenspire when I get an error (304 maybe?) that my account is already logged in. This kicked me back out to the Title Screen. This is after the game going to a black screen once and forcing me to quit out and attempt to log back in again all while I've been battling with "unexpected internal errors" for 30 minutes before finally getting in. Now I'm battling with those same errors and long, broken queues. Sometimes I'll be in a queue for 5 minutes before it tells me an error occurred.
The game itself is great but these log-in and connectivity issues are ridiculous.
