Hey Werner, I need your technical knowledge on something.
I'm attempting to make NSM4 ROW-compatible, and it looked like a pretty simple thing to do. Here's a breakdown of what I did with a side-by-side comparison of the two zones.cfg files with Winmerge:

1.) All effects from ROW copied over to NSM. If any NSM effects are present where there are no ROW effects, they stay.
2.) Cargo types in NSM replaced with ROW; I also added some extra cargo types present in ROW, and some Weapons compartments, floatability adapted to NSM with a ball-park estimation
3.) Crush depths copied over from ROW ONLY IF effects copied over as well.

Using this file, I stumbled upon a pretty nasty side-effect yesterday night when I was playing my campaign: I discovered that, if my sub is too close to a merchant and its keel gets blown off, my sub literally disintegrates! All of a sudden I start getting damage everywhere, and after a bit the game CTDs. I know it's right after the keel exploding, because I'm using some torpedoes that pack a pretty punch (all values in your torpedoes_US.zon file x2, essentially, just something I'm testing out), and though the fish hits at the bow or stern, it sets off a chain reaction that literally blows the enemy ship to smithereens...which is all fine and dandy, but if I'm closer than approximately 1000-1500 meters my sub bites the dust as well!

Do you have any idea what could be causing this? The ship's cargo, perhaps? Another member posted something similar a few posts up, and you attributed it to the enemy ship carrying ammunition. Anything that can be done about this?

ETA: I know I should have done more tests to pinpoint if it's something in NSM's zones file, my Frankenstein's monster, or my torpedo settings that cause this, but I quit the game at 6:20 in the morning, falling half asleep on the keyboard while sailing home, so further tests were plain impossible! BTW, whatever happened to your test mission? It would've been quite useful in this occasion.
