Ink black shadows on foliage

I would attach screenshots but this site isn’t allowing it right now for some reason. Anyways, my trees and shrubs suddenly have ink black shadows on the underside of their leaves. Things I have tried: Yes my sun and skylight are set to movable. I trashed my save folder. This happened once when I enabled mesh distance fields on another map so I enabled and disabled on this map and no dice. I don’t want to uncheck lower hemisphere in my skylight because I like that effect and it is not causing this issue. The issue persists whether or not the skylight is engaged. Anyways, I have a visual presentation meeting with a publisher on friday and I really need help as soon as possible. Thanks in advance, J
