A Calculated Humidity Ratio= -410.2300 warning occurs in the err file for the DOE reference model StandAloneRetail. This is one of the DOE reference models WITHOUT modification, so any idea what's wrong?

Strangely, the warning only appears for the last design day in the model, but if I delete the offending design day, then a different design day is referenced. I think the error is occurring for all design days, but Energyplus is only reporting the very last design day in the IDF file.

Here is a google drive link for the zip of the idf and generated files.

Here is a google drive link for the idf that has been significantly cleaned up with different design days.

Both the err files have the same warning.
