I think (I hope) I'm not alone in my struggle with advanced spacechemistry, so let's gather here and help each other out with the tricky assignments.

I'm currently on Suspicious Behavior and utterly failing at finding a workable solution. When I started out I was able to progress in assembling the molecule by bolting on cycle after cycle to move that giant molecule where it was supposed to go, but doing that I inevitably run out of space.

So on the next complete do-over I tried to pre-empt that by moving the first subunit as if it was already full-sized and alternate which atom gets bonded by each waldo - red grabs delta and bonds to carbon, blue does the opposite. It looked promising until I realised that with each of the waldos occupying a subunit bonding cycle at the bottom of the output window - it can't go higher because that would bring the finished molecule out of bounds - it's impossible for both of them to drop the subunit either early or late in alternating cycles, which is necessary because it has to be bonded alternatingly right of the middle and left of the middle, and I only have two bonders arranged vertically in the output window. The other two bonders are in the input window and are required to assemble the subunits. I can't assemble the subunits in the output window either because they'd inevitably collide with the molecule in progress.

In short, I'm out of ideas. Does anyone have some pointers?
