Pond tool won't freeze in winter / icy conditions

Pond tool will not freeze over in winter, even if the weather is set to snowing and icy conditions. Snow shows up fine on roof or other objects, but the water remains the same as during another season. I have tried this in both Snowy Escape and Windenberg world, and both do not work. I also do have Seasons installed.

I'm on a mac book air and tried using both the low and ultra settings for the graphics. I removed all my mods/CC and I even re-installed the whole game through origin. Nothing seems to be working. Is this a bug? Or is my laptop not strong enough to handle the graphics?

I attached a picture of what I'm seeing in Windenberg.
