[Dead Mans Hand]

Just started playing, was a big fan of SHII, anyways I found myself in a peculiar scenario today. I took four bloody torpedos to sink a merchant vessel. That's only two less than what hit the Oklahoma (Or was it the Arizona.) The placement was not bad of the first two one it midships, one about four meters closer forward towards the bow both from port. The next one from my aft tubes straight up the prop from behind her keel, and finally another one in the midship on starboard.

Is this a bug or is it that touchy about placement?
