DESTROYED WINTER: Snow is flat, no depth. Snow looks like white paint on the roofs.

I have to agree but sadly what we have here is one of the scenarios that it is evident that Sims 4 has limitations and that comparison from Sims 3 Seasons and Sims 4 Seasons does not shine a good light on Sims 4 especially at this time being Sims 3 is older and its features surpass Sims 4 and it makes Sims 4 Seasons look like it was designed on an tablet.
