Welllll... the damage sub-system (purposeful play on words there) is a "deep" (and again - sorry, won't happen again, until the next time) subject, and is most likely beyond my "depth" of understanding (I can't stop, sorry)... but we'll give it a go, and try some comparisons between stock and a few mods, and see if I can notice anything that isn't at the least tied to a visible "damage", whether repairable or not. At the least, to know that it's damaged... I do remember reading about this, and I'm wondering if it was mentioned in Traveller's mod - but the details are elusive...
