I've been messing around with custom faction's Extreme Foremen/Planet Menders combo with starting Sower population, and everything was working fine—I was boosting both to change the custom's +0.5 Depletion to +0 Depletion and the Sowers' -0.5 to -1 and had completed a few such boosts already—until turn 80 (Endless speed), when a boost ended, then suddenly my custom faction was removing Depletion points at a rate of -0.25 instead of adding and my Sowers started adding Depletion points at a rate of +0.25 instead of removing, and my output file started registering an error for a fleet mission it couldn't find...the output file and the save file are included here!
