I dont feel like a betatester with this perfect mod! It might be too perfect ... while i was in a duell with some escorts i increased the volume and turned my ear close to the speaker to figure out what one crewmate was complaining about one of them damaged my tower running over it.
There is 1 thing about the alarm of solo escorts which are fighting the sub for hrs. Im no Navyguy but shouldnt be it in a permanent state of alert during the fight so no extra "on battlestation alert" should be necessairy. Everytime i fired on it after 20-60min i could here the sound.
