I wasn't quite sure where to post this, but I guess this is the right thread:
Since there are multiple variations in the day/night cycle of the city, I'd like to know if there's a certain regularity about them, and if yes, how exactly they occur and if it's really based on an in-game "week" schedule:
DAY: Purple/blue sky / Sati's sly (I've read it was each 7th day, but not sure), raining, raining with lightning and thunder
NIGHT: Clear, black sky with a moon and stars, "overcast" sky with something like clouds moving over the sky as if it was smoke (was also in the first EtM cinematic)
Although HCFrog told me something different in the Update Discussion, some nights seem to get darker than the others, although it somehow isn't obvious to me.
I know I could find out myself, but I couldn't find the time time to play the game for hours and check this issue and then look if it really occurs exaclty the same way on the next round. If anyone had the time to figure this out, please post it here.
