KarlEngler - I can tell you what happened, just not sure why it happened. The decay on all your feeder colonies increased dramatically, causing the value of the minerals they send to your core world to drop. The drop in your Planetary Input from 40.7 to 27 caused the Planetary Output to drop from 192 to 129. Formula used in calculating Planetary Output is based on compound interest, so a small change can become a big one if you have a lot of factors compounding. I can explain how this works in a PM if you're interested, but like I said I have no idea why the Decay increased. I'm not seeing it in my game, but I'm playing an updated version (Insider 155.376713).
