Thanks! This looks reasonable on first glance. Would you mind creating a test that exercises this edge case?

Hi @djarecka, thank you, I will add them by the end of this week. I have a few other things that I need to take care of first

@djarecka, I spent a while on this, but I was unable to generate a case that triggers if op_single in self.inner_inputs. Would you kindly help me? I think I would need to spend more time than I have reading Pydra source code to know what to do here
