Update: I've found this post talking about water effects and DynDOLOD. sheson 13 Jan 2019 I have explained this many times: DynDOLOD copies the highest overwrites to create records in its own plugins. This includes the worldspace and cell records that define the default water in the world and the water in each cell specifically. If a mod that changes any of these is added later, it will have to be loaded after DynDOLOD plugins or you need to create new DynDOLOD plugins for the changed load order. I have RW2 loaded after DynDOLOD, but I can't remember where I had it when I last ran DynDOLOD. I'll do some tests this week and see if that changes anything. Not sure if that's the correct path for this issue but it's all I could find.
