I d(idn't)on't have any mods affecting water assets, so its unrelated mod,  likely an author deleting it by mistake. I had open plugin slots and tried to install Realistic Water Two SE, but still missing. Already tried verifing cache.   https://www.nexusmods.com/skyrimspecialedition/mods/2182?tab=description   Can anyone tell me where to find this section of the river in ssedit so i can check what mod affects it?
