Can't seem to export as an image without losing half the flow chart

I have a flow chart with roughly 831 nodes detailing a narrative that I can’t seem to get to export to an image type without losing the second (roughly) half of the flow chart. Is this a size limitation on scapple? Or is there something I’m doing wrong?
->create flow chart → file → export → as image → all formats lead to outputting an incomplete flowchart
