std_NPV being produced as nan

Describe the defect
When a HERON case is run on the HPC in the opt mode, the std_NPV is being reported as nan. This issue has started after a recent RAVEN update.

What did you expect to see happen?

std_NPV has been reported as a number for all the cases run up to the point before RAVEN was updated. Upon running older cases which had std_NPV reported as numbers, their std_NPVs are now generated as nan

This has been tested on another user's machine as well.

Do you have a suggested fix for the development team?

Describe how to Reproduce
Steps to reproduce the behavior:

1. Update RAVEN
2. Run a HERON case
3. Check std_NPV
