The thing about Organic armor that was fixed for gold was this:
Now, any OA component can heal any other OA component.

Before if you lost all examples of any component with OA ability, you would lose all OA ability for that combat.

That means, if you had one OA II on your ship and 15 OA III's, then losing the OA II at any time would make you forfeit all you regeneration abilities.
In Gold, you can now use more than one type of OA component, and have it always keep working. This benefits mods mostly.
