I notice (and in the XML) that if the Consortium corrupts your planet, your unit are 10% cheaper to produce (playing the Empire).
I thought that corruption was to make production cost higher, not cheaper

? I notice it does change production speed 0.95 a little.
I seen that if you remove corruption on a planet with Corruption Milita, the planet will revert to neutral and you lose your buildings and space station, but your single units will move to your closet planet.
