Seemed like the general consensus for a Northern Roads - Seasonal Landscapes Patch was that it was on the docket of a long list of cohesion patches that needed to get made. I personally had a big use for this one and had nothing going on today and dug into it. If it works well and the Northern Roads Patch Team wants to take over support that's fine I just have no confidence in it being all encompassing perfect working right out the bat and feel bad throwing them a potential whirlwind of support. Not for Seasonal Landscapes Unfrozen just yet but since I figured this out I think I should be able to go about doing that Patch the same way just give me time to go through the inis. 

The Problem:
Northern Roads edits landscapes all around Skyrim, Seasonal Landscapes in it of itself doesn't edit landscapes physically as in it doesn't terraform anywhere. It does however alter what grasses grow on certain landscape textures for seasonal changes. This problem can be mostly fixed with the Grass Patch Northern Roads has but the whole basis of Seasonal Landscapes is that it changes each season and that's where the main issue arises; The Seasons ini for Seasonal Landscapes has many instances where it changes something that's flagged NoGrass into some seasonal variant but covered in grass.  Couple Northern Roads landscape editing with these aforementioned seasonal variants, you get many instances where grass grows out of roads or elsewhere it shouldn't. 

Solution:
First, use the general grass patch thats included with Northern Roads to clear up the NoGrass Lists. Then in the Seasons ini change the seasonal variation; wherever a NoGrass is changed for a season, make sure a NoGrass is changed into. 

Note:
I personally use Water for ENB and with the Northern Roads - Water for ENB Patch a certain patch of grass in Riverwood refused to go away with the method above. For Mod Authors or those who Care: (I think it had to do with a Quad that already had the max 6 Textures and it needed FieldGrass02NoGrass mixed over the road but due to being at max FieldGrass02 just got thrown everywhere--if anyone can help me repaint where FieldGrass02 gets applied ie. erasing a small part in the Water for ENB Patch that would be massive.)

I have included an optional file that you should overwrite with the main file if you use Water for ENB. I think I fixed the Riverwood spot but I anticipate there being more like this so please let me know in the comments or PM if you find any. 

A second optional file fixes a couple landscape seams that I found in the main Northern Roads mod and also a couple Water seams from the Water for ENB patch for Northern Roads. Figured both of these may be fixed in their respective main mods but this is a temp fix to make it look okay in the meantime.
