Hello again!
I was able to fix this issue, appearantly when you start it says 500 (m) pop at start and if you change that to 1000 (m), it changes the conventional construction number to 1. 600 wich it accpted as 1,6 wich is nothing so contruction was so slow. . . not working as intended?
Now I have another issue seems that when I changed to 1600 now its giving me 160000 BP at the start of the game so everything is done way to fast ( I know first world problems ) when I go back to 1. 600 it does 0 again. . .
I have fixed the date problem as far as I know
ps; also will make account apologies
