David, When I try to make value adjustments "on the fly" with the final components (far right) on preview, rhino and grasshopper will crash and not even prompt for an error report. I have altered the definition so that it isnt as memory intensive. I dont know if this is related to the file reading issue. Please find the following files for your reference:
