Bug in ModuleResourceHarvester, HarvesterType = 2?

[seanth]

I've been trying to make a part that would extract gasses from the atmosphere, but the rate/sec of extraction continues to increase over time. It seems like it should remain constant if the extractor isn't changing altitude or anything. Crustal resources don't continue to increase in amount/sec when you use drills, for example.

Mods installed: Module Manager, Astroid Day, BioMass

Out of curiosity I installed the Karbonite mod and looks at how the atmospheric extractor in that mod functions, and it shows the same behaviour.

I'm including some snippets to show how things are setup:

PLANETARY_RESOURCE
{
	ResourceName = XenonGas
	ResourceType = 2
	PlanetName = Kerbin

	Distribution
	{
		PresenceChance = 100
		MinAbundance = 0.934
		MaxAbundance = 0.934
		Variance = 0
		Dispersal = 0
	}
}

    MODULE
    {
      name = ModuleResourceHarvester
      HarvesterType = 2
      Efficiency = 1
      ResourceName = XenonGas
      ConverterName = Xenon Filter
      StartActionName = Open Xenon Filter
      StopActionName = Close Xenon Filter
      INPUT_RESOURCE
      {
        ResourceName = ElectricCharge
        Ratio = 1
      }
    }

And here is a very short video showing what I am talking about:

Is this expected behaviour for atmospheric extraction, or is this a bug?

Were you able to solve this issue?

For me, this levels out at some point.
