**Exception Message:** 'NoneType' object has no attribute 'copy'

Posted this in a previous issue but realized it probably needed its own report.

I've been using the same workflow for months now with only minor issues every now and again with updates. These most recent updates however, have seemed to break my workflow when I attempt to use a refiner/resample.
