I was testing out this mod, and so far it was beloved by people on the server that I was managing.

However, there are some compability issues or so it seems.
We have Weather2 mod, to imitate wind, sandstorms, tornadoes and etc.
And during the winter, Snow doesnt seem to "fall".
We see Water freezing, but no snow layers on the ground.
Not sure if it's working the way it is supposed to, but I heard that usually snow should generate.

They likely still don't support Serene Seasons, and it's not something we can fix on our end.
