For whatever reason, if your sub takes damage during a session, and you save that session, no matter what caused that damage in the first session, it is heard all over again when you reload... very strange behavior. You might also hear a "Passing thermal layer" if you did that... But damage from an anti-subnet will cause the scream of the banshees in your boat, every time after when you load that Save game... Keep your ear cans off, and the speakers turned down when you re-load. It is also better to make certain that there is no damage to your sub when you go to Save, else you may end up with it right back where it was when you first incurred the damage. One of several weird parts of the SH4 Save "System"...
