Frost layer deletes grasses and ferns.

I recently came across a problem where frost applying frost would remove ferns and grass while tall grass, tall ferns, and flowers remained. Any ideas why this is happening?

Using a custom ground cover layer does work, but then I no longer have snow covering my objects.

EDIT: So I found a way to do it but is it worth it? Probably not. Use a ground cover layer for the snow and then cover all your schematics with snow and re-save them. You'll save the ferns and grasses but loose your sanity. Best way to go about doing this is by pasting all the schematics in a flat world, make a selection encompassing all of them, and use this command to cover them {//replace ">spruce_leaves air" snow}. I wish you fellow grass and fern lovers good luck!
