Hi,
The game claims the formula for the decrease in food production is:
My nation radiation index is 20.69 at the moment - food production is reduced by 4.51%.
20.69 / 1000 = 0.02069
Multiplying by 100 results in 2.07% food production reduction - much lower than 4.51%.
I solved 20.69 / x = 0.0451 which resulted in x = 458.758315
I then repeated the same for a few other continents:
North America: x = 347.860963
South America: x = 676.587302
Did the formula change or is there a bug in the system?
