I am also having the same manpower issue but a short time after the option goes negative my game starts to have graphics glitches and lags and then the game crashes. This only happens after i use the manpower option and the stat later goes from 1b to -1b. I've attached my save file to hopefully help out. Thanks for your time and all your hard work!
