My restarted 1.9.0 game - created and played with the correct decimal separator - seems to be bugged after updating the exe to 1.9.1
On opening the economics tab i get a 2186 division by Zero attempt
In the first load, the racial Wealth also showed 0 and a negative income.
I closed the game and restarted, the Wealth and income were ok again regarding the numbers, but clicking on economy still gives the 2186 divide by Zero Error.
Short Campaign, only 3 years passed, no Errors previously.
