An old message on this Neural net page states that the Congress have been granted docking permissions:
Falster Administration
Dear Managers of the Junkers Congress, the IMG has never had trouble with the Congress Junkers. Access has been granted for all ships. Good luck.
Irene Thompson, Secretary of the Guild Masters
Today, I flew in the Omegas, and I tried to dock on Falster to see what is on sale, but my docking request was rejected. I'd like to ask if the previous permissions expired, or did some incident happen that caused the permissions revoked? I'd like to renew the permissions, and I'm willing to pay the proper fee if required.
Thank you for your answer in advance.
