Water polygon preventing snow formation

Do you have any add-ons in your Community folder? If yes, please remove and retest before posting.
Are you using Developer Mode or made changes in it?
Brief description of the issue:
Working on an update for one of my sceneries in Alaska, I encurred in this issue, which WAS NOT PRESENT before the UK Update. Adding water properties to a polygon, creates an area surrounding the pond/stream/lake/whatever, with green summer grass. I wonder if Deer lick the snow to reach the frozen water? :smiley:
Provide Screenshot(s)/video(s) of the issue encountered:

Detail steps to reproduce the issue encountered:
Seems pretty random and zone-related. Add a polygon, flag “water”, whatever type, save, build, and try both in DevMode and Community Folder. Snow won’t be where it should even with 100% coverage
