So, sometimes part self-destruct. It says in the log that the part "fried", and it's gone. Did it fry itself completely?
Maybe it should leave some matter, to represent that it left at least something. For example, ΒΌ of it's integrity.
Maybe sometimes they not just vanish, but become broken? Player still can't use it anyway, unless they fix it. These would be more accurate "fried" parts. It's still there, just not working.
By the way, I'm not sure if this is explained in the lore, but why picking up self-destructing parts prevents their self-destruction? Are they only self-desctructing when on the ground, and as long as someone carries them, they are fine, no matter who it is? Then shouldn't they self-destruct if Cogmind picks them up and drops them again? Or do they only self-destruct when the robot carrying them dies? Well, I'm sure if someone who can attach it (scrapoids have scrap suits, which would autoattach parts into free slots, but I'm not sure if they actually can) dies afterwards, they won't self-destruct... how does it work from the lore perspective?
