Playing as the US, I've seem to run the game to ground in 1877. I am out of Coal and Manufactured Goods, with no way to get more.
I have every coal pit and manufactured goods factory built. All of them are at maximum production in 100% developed regions with railways. I've turned consumer consumption down to 10%. I have closed every non-essential production facility that is using coal or manufactured goods. I am buying the maximum allowable off the market.
Yet I'm still stuck on -100 coal, and 0 manufactured goods, and have been for over a year.
Too bad, its a fun game and I was doing well.
