Ok, so it's not only me- I was beginning to wonder if they were a mod, obviously not. It might be worth mentioning that I used the deck gun on a couple of those targets, so in those cases the whole boat had taken loads of damage all over before going down, maybe I got the crew before I got the boat.... I have resorted to the deck gun a couple of times as my torpedos have gone south, having trouble hitting the broadside of a barn at the moment. All good though, am loving SH4
