I'm building a scenario in which an Improved Kilo (AI) attacks two surface ships.
About 1/2 the time, when the Kilo launches torpedos, one of the torps seems to explode immediately after being launched, sinking the Kilo.

I believe the torps involved are wake-homers (53-65), but am not sure.
I'm running DW 1.03 stock (no mods).
Any ideas?
