By binary-binary, I mean two objects orbiting each other, another two objects orbiting each other, and then both of those pairs of objects orbiting each other.
Basically, creating this doesn't work. I've tried everything, including every possible use of the "make binary" action. The two pairs just fall into each other.
On top of that, trying to make two objects in a binary orbit around a single larger body doesn't work either. They have the same problem where they'll just stop moving and fall towards their host body.
Getting single objects to orbit larger binary objects works just fine. Same with three similar objects (two in a binary and another orbiting them). So why don't these things work?
