Weird bug in selection denominators

[ebrintn]

Every once in a while I get this, I can rerun and it works but I think that there may be an issue somewhere in calculating the selection denominators

Traceback (most recent call last):
File "/home/erin.brintnell/.local/lib/python3.6/site-packages/pandas/core/indexes/range.py", line 355, in get_loc
return self._range.index(new_key)
ValueError: 49 is not in range

The above exception was the direct cause of the following exception:
