I managed to get a hit on this destroyer.

The "weird" thing was that the ship maintained same speed as if nothing had happened? After a long time the ship eventually sank.

Is this normal behavior with this mod?

You're not the only one this happened to. Alhough in my case,the ship never sank at all: http://shroomworks.deviantart.com/ar...F49997610&qo=6

Not sure if it's a bug in the game itself ot a bug in the mod,but as far as ai can tell,it's very rare. I've sunk many ships and it only happened to me once.
