Attempted to put a complex molecule into a rotator demo slot.

Ah - the way the demo section inputs work is that they (currently) only hold the item name, which means that complex molecules don't have any contents as demo inputs

I think I have an idea of how to fix this to allow complex molecules in demo inputs

Roger that. I just had another crash applying a complex molecule to a demo slot on a bonder as well. I assume the demo issue applies to all on the machines with demo slots. Here is the crash report anyway. JIC
