I just found the likely cause. I had Grass Cache Helper NG active since its one of the early mods in 02-Extenders. The mod page says: A- This mod enables loading grass instead of creating it at runtime. If all your grass disappears, one of these things happened: - You don't have a grass cache installed (.cgid files that can be generated with NGIO). If this is the case, you need to generate grass precache or install an already generated grass cache downloaded from here on nexus. Not sure if enabling the mod Grass Cache Helper NG. Made the grass disappear and much later in the guide when it's time to generate precache grass it only took me 9 mins to do because the grass were never there in the first place.

Finally at STEP 6. Benchmarking, No grass visible. I followed everything word for words. When I launch the game through Steam the grass is there. But when I launch SKSE through MO there is no grass, Grass precache only lasted 9 mins to complete. I followed everything in NGIO guide. seems like bricked.
