We're just getting warmed up, wait til we start selling tickets!
Turned the voices back on, I get "yes sir" followed by another "yes sir" in a different voice with "CE snorkel depth" on the message screen. Hitting the ' key I get "CE rudder amidships" on the message, voices "yes sir" followed by "rudder! rudder!". With all the other bugs in this game those are merely minor annoyances, easily cured by turning the voices off. When these lubbers persist in saying "yes sir" where they should be saying "aye aye sir" I don't really want to hear them anyway.
