Not a Bug I guess
its the Kaleun who gives the order ''Fire At will'' so they will shoot any target in the area.
must be SH3 , because I guess the fire at will feature will respond onto any confirmed contact in the area.
tot test it out
start in a harbour and just press the fire at will button see if the Deck Gun crew start to shoot at the ships in the area thought they are friendly or Neutral (you can find some neutrals in the harbour) if the Deck gun crew start to shoot at friendly and neutrals then its clear the it responds to any contact and shoots at it.
