• In theory, you will no longer be penalized for aborting a courier assignment to a destination that will not allow your ship to land. The message from the clerk will reflect this. Please REPORT any tracebacks or unusual behavior.
• Courier companies have had their relationships updated and should now be allowed to dock with all alliance's space stations and planets, as well.
• If you have permission to enter a house you can now register with the mailbox at said house.
• Fixed a bug where your ship would claim sector 0 was invalid if you tried to go there after viewing the FTL map.
