The bug/fix I saw reported (not by the dev) was in game/script3.rpy, line 2243, replace
$ pollutionChange(1-prodpoll)
with
$ pollutionChange(prodpoll)
That’s in the year end code. prodpoll is some value that starts at 1 and is reduced by things you do to reduce pollution. But with the original line the more you do to reduce pollution the worse it gets.
I think your catch
is a problem too: lecturess is your fame as a professor, and poptt is the number of people in the town. It makes sense that the more famous your are the more influential your writing should be! Except of course the other bug makes being successful worse for the environment…
Ill pass it on.
