I think I have discovered the problem. I changed the decay rate to 10000 and it did nothing. Just moments ago I changed the decay rate to 100 billion. That caused an error when loading up, but didn't negatively affect the game. After the next turn, my inflation went down to zero. I think what is happening is that I am on eternity speed, and the decay rate for eternity speed is misconfigured so there is effectively zero decay per turn. Besides A_New_Dawn_GlobalDefines.xml what files control for hurry and inflation?
