We discovered an issue where ship plans are only available to the person who used the item from the NPC. I list this as a bug because all the rep and other items can be shared amount the friends on the server. Unlocking hull plans should be server wide. or the option to share them should exist. Requiring every person to buy the same item is a bug.
#Ship plans are only buildable by the person who used the plans.
