Input file header dropped when writing external?

[wkitlasten]

Hi,

I use external files, which often contain headers with # comments. I have noticed lately that those headers are getting dropped from some (ghb, wel) but not others (sfr) when the simulation is written. Is this intentional? Am I imagining things?

sim.set_all_data_external()
self.sim.write_simulation()

Cheers
