Easy way of getting around the problem is to say the lift motors were the ones used to move the castle from the Moon where they were grown (IIRC) and now perform station keeping/stabalisation. The rest of the controls deal with pumping the lift gasses around to balance loads (or evacuate ruptured cells so they don't loose all the gas to Venus) and emergency hatch overides.
I'd expect them to completely destroy the emergency cable jetason controls. That way as Crystal Osaka looses lift, the weight of the cable helps drag it down.
Edit: How long do we think it'll take to sink, once started? Given the distance some people will have to travel, maybe a day?
