WARNING - Writing a minimal INP file without saved non-WNTR options (energy, etc.) -- obselete?

[angusmcb]

Summary
Each time I run a simulation using epanet I get the following warning (generated here):
Writing a minimal INP file without saved non-WNTR options (energy, etc.)

I wanted to see what other options weren't written, so had a look at epanet/io.py.

As far as I can tell, the energy is actually written. Therefore, I think this warning is obselete and no longer correct?
