ordering/diagram not rendering correctly

[brahn]

This might be a continuation of #64 --

I am trying to render the diagram with the input included below. If I comment out all the "positioning" lines and check the "hide numbers" and "sort nodes by line number" I get this graph, which seems reasonable --

However, as discussed in #64 I want to lay out the notes in a specific way. My intent is that the positioning lines (along with the sort nodes option) would make this work. However, when I uncomment the lines the diagram doesn't seem to change in a sensible way, and I see errors like this in the browser console:

If I refresh the webpage and enter the input afresh (with lines uncommented and with the same settings checked) I see the following (along with similar browser console errors). For what it's worth, the node positioning is almost exactly as desired -- excepting the absence of a visible Nov_6_A node, I see:

• First column contains all Oct_09... nodes, second column contains all Oct_16... nodes, etc. through the last column containing all the Nov_6... nodes.
• All the ...A nodes across the top row, ...B nodes in the second row, etc through ...E nodes across the bottom.
  But of course the "flow" shapes are missing.

Any tips on how to proceed?
