You know that red stream that tells you the flow of a graph?
I’ve noticed that if you collapse some nodes, that stream won’t show for any node directly connected to the input or output of the collapsed graph, both inside and outside of it (see attached pictures which hopefully make more sense than this sentence).
I can see the coordinate system being drawn, so that function is definitely called, but you can’t see it called in the simulation.
I’m assuming this is not by design, since it turns collapsing nodes into a very bad idea, debugging-wise.
