I still think your fix (reverting to the 2010 values) is probably the most appropriate one.
I'll copy the patch across to NOx2018 in #738

@rwest
Revert from Burcat 2014 to 2010 for HOCHO in NOx2018
a64a183 
The values used by Klippenstein and Glarborg in both the
Klippenstein_Glarborg2016 and the NOx2018 thermo libraries
have a discontinuity in the curves.
Apparently after Ruscic modified the polynomials some time between
2010 and 2014 versions of Burcat's compilation.
See #703
and #704
for details.

To address, we revert to the 2010 values.
