SH4 suffered from the "zombie" ship bug - you could sink a ship - and a few hours/days later - run into it again. This occured if the convoy it was attached to changed its path via waypoint. What occures is the ship is "respawned" to get the convoy back to where its supposed to be. The problem - its now unsinkable.

An example is I sank a CV in a NSA - then ran ahead on the convoy course. They later formed up and returned to their base course, then zigged away - leaving me in left field - literally! I couldn't catch them (though I tried) - and ended up turning and heading back for my original hunt grounds. As I did, what do I see but a lone CV, running max speed - in pursuit of the convoy (though I didn't realize it at the time). Due to the speed, I shot a full spread - 6 torps - 5 of which hit. All exploded, and "visible" damage was present. No death.

I had actually saved right prior to the lone cv encounter - so I tried again and again - the thing wouldnt sink. Finally I loaded a nuke torp (damage 5000, area 750 - meaning three quarters of a kilometer) and reloaded. The first time 3 torps hit - and the CV kept going. I wondered if the mod took - so reloaded again, fired at minimum range - and hit the gas. I was 638M away from the impact - and I THINK 3 torps went off. I know I heard two - and when the third went off, I was dead. So I reloaded again, shot a full salvo - 4 hits - it kept going. With the specks on the torps - Yamato would have died with one shot. This was how I confirmed it as a bug.

Note - if your running any mods - many of the big ones include changes to the ship flooding and structure model - as well as cargo. In fact, I think - and I could be wrong - but I seem to remember some diabolical fellow actually set some freight to be like cork - and ADDED bouyancy - making the ship with that cargo almost unsinkable.
