This change had to be postponed due to certain technical complications, but is now fixed and will be included in the upcoming update, so I'm giving this notice a bump:
If you currently own a Barge, make sure its hold is empty. If your Barge is corrupted after the release due to exceeding cargo limit the admin team will not restore any goods or items you may have had on that ship (note that unmounted equipment still occupy cargo space and so fall under this notice. Move any cargo and equipment off the ship).
