Yeah, I'm on XS4ALL (thru WiFi because of a router refusing to configure nicely to allow for WDS) on this box, and I can fly fine on Jagerstadt since Blacklung got me there, but the Zweihander sector isn't working.
Also, technically I am 'multi-clienting' since account 1 runs on left screen and account 2 runs on the right screen. Regardless of whether I just run one account or 2, the same issue persists.
