The adjustment to research costs is obscene. 2.2 billion is excessive for max research. I control all of China, the wealthy parts of the Austro-Hungarian Empire, Germany, Poland, Ukraine, and ALL of China, as well as half of korea, and I can't afford jack or shit.
Specifically: the costs aren't lining up. If I set research to 0, I have +2,304,793,000. If I set it to maximum (says it costs 2,256,659,000) I get -2,208,525,000. I SHOULD still have a positive income. It costs nearly twice as much as it says it costs.
