Is it intentional that the ligand is locked in place?
I'm a new player, but in the previous design puzzle it was possible to wiggle or manually pull the ligand into an optimal location. Right now, it still seems to be possible to wiggle it around but at a drastically reduced rate (.001 per second about, for as long as you care to let it run).
The result is that I've done about 15 seconds of design, and a few hours of letting it wiggle as it is the only way to move things.
