all upgrades are affecting your stats to the power of three right?
so if i have a base up of 1000 and level 30 charisma my total up is
1000*1.3*1.3*1.3=2197
but income only seems to be affected to the power of two
so base income of 10 mil and level 30 production only gives
10,000,000*1.3*1.3=16,900,000
instead of 21,970,000
