Jumping in with a related question here - in my TMO games, there's a crewman you can 'buy' who converts two of the ballast tanks to fuel tanks to improve surface range, but whenever I've 'bought' him and taken him out, it says 'skill disabled'. Come to think of it, it even says 'skill disabled' before you 'buy' him from the crew screen. He's in the right compartment, though I forget which one.
Anyone seen this, any ideas?
