I finished my campaign, but I almost screwed it up. I had made it to the last step without any pushback really. My resources were good. I think I was around year 50 when I hit that step. Then I got careless. I was just keeping a cursory look at my resource levels as I was playing at 16x speed. I lost track of how much aluminum I had at separate bases, so while I thought I had plenty, my main developed area didn’t have much and I lost around half my workers. Things screeched to a halt.
I went on a mad dash deleting unnecessary things, much got me some resources back. I made my way to new aluminum deposits and got that flowing again. But then I wasn’t paying much attention to power because after building more buildings I started running negative. I had temporary swings so I wasn’t worried, but this one wasn’t temporary and it drained my batteries.
I went on another spree deleting things and building nuclear power plants. Now I lost track of my carbon and electronics stock and I lost almost all my maintenance drones. Another mad scramble. After pairing down things that were no longer necessary, shoring up production, I was able to let it run until I finished terraforming the final step.
