Ship weapon effectiveness

Cubey

I've just attacked a pirate autofactory and its defenses didn't take any damage from EM weapons, only thermal ones.

Is this intended? They don't have shields so I assumed they count as organics. Or is this an unintentional side effect of the recent change that made EM shots unable to uselessly pierce barriers? (That's a very good change btw)

Noticed this as well.

Also, I wish em piercing would backfire a system, not that em rounds get reduced to a singular useful event
