Hi,

Seems that maximum pop is not calculated properly on Volyani, also affects Volyani affinity custom faction, just see image.

The max pop of that system is 36 (9 from each planet with Level 4 Ark), but the system thinks that could be 12 per planet.

Seems has something to do with calculations priorities, the planet max pop value is set to 9 then some other calculation (didn't find it) adds 3 more pop to that value.

Fixed upping the priority from 1 to 2 on the lines that override planer max pop with ark value. Tested on an endgame save and now Biofuel Factory works properly.

public/Simulation/SimulationDescriptors[ColonizedStarSystem].xml, on "ClassExploitedStarSystem":

        <Modifier TargetProperty="MaximumPopulation" Operation="Force" Value="$(MaximumPopulationFromMothership)" Path="ClassExploitedStarSystem/ClassPlanet" Priority="2" TooltipHidden="true"/>

        <Modifier TargetProperty="MaximumPopulationFromMothership" Operation="Force" Value="$(MaximumPopulationFromMothership)" Path="ClassExploitedStarSystem/ClassPlanet" Priority="2" TooltipHidden="true"/>

Hope it helps!

Just had this problem in my Vodyani playthrough as well.  Thanks for coming up with a fix!
