Hmmmm... Ok I'll give that a shot. I have open cities so I don't have to worry about the resets haha =p I appreciate the advice though, I will take a look. Could it have somthing to do with my timescale being set to 5? Are there any new settings added in 1.0 that I could play with to see if it helps?
Yes, if your timescale is low the weather will take much longer than if it's at vanilla 30. If the CS values are to be believed (and they could be wrong...) the Gate weather takes 15 minutes of game time, which at timescale 30 is 2 minutes, which is a lot slower than I get at 30, so the CS values for that aren't to be believed after all...
Anyway, if a weather takes 2 minutes real time to transition at timescale 30, it's going to take 12 minutes to transition at timescale 5.
There aren't any relevant settings that you can alter to change this, if your game goes at a slower speed, it's going to go at a slower speed. You can change your timescale to something higher, but presumably there's a reason why you have it that low. It's not an AN-specific thing, in any case, this happens in vanilla too.
