So upon joining a Multiplayer session you get the normal character creation screen and when you Click play it pans up to the sky and then just sits there and does nothing.

However we worked around this by using 'LogMeIn Hamachi'. I imagine other LAN like programs that simulate a LAN network bypassing port-forwarding ect would work too. I've attached the output_log for a failed connection to a 'Global' session. output_log.txt
