If the simulators are gone all that is left is a bunch of useless electronics. If they used the parts elsewhere then it is only logical that they took the working controllers out and sent them along with wherever the simulators went. I don't know, but, gutting doesn't mean you take the the door knobs with it. Gutting means that everything that is a crucial part of the mechanics is gone, then it is no longer ever going to be restored. In other words I don't have an exact date for when those electronics left, but, it is irrelevant since it is no longer anything but a room with nothing useful in it, like a storage closet.
As far as I know, the stuff for CC is still in place, show set wise, that could have changed, but, that means nothing really. It is an area that they aren't using. It ends up being as good a place as any for it to sit and that there is no need to spend the money to tear it out at the moment.
