Wrong or poorly worded message.
Solved
When adding a wheel i get message "piston head already exists"
When trying to complete a contract from the character's inventory i get a "selected ship" does not contain items.
Could you please rename the messages to be more appropriate. A wheel is not a piston head and a player is not a ship.
I have the same bug
