Today I ran into a bug somewhere in the coast of Dawnstar. There was a huge block of water missing that could only be seen from a distance. I googled for a fix and found xLODGen. I looked up how to use it and generated Occlusion.esp. I put it last in my load order, launched the game and the problem was gone. Ofcourse there's a but: My map now looks horrible. All the bodies of water look blocky and the roads from my map mod are gone. I deleted Occlusion.esp but the problem persists. I also disabled everything that I had generated using DynDOLOD earlier just in case but the map is still looking the same.
I'm quite new to this aspect of modding and I'd like to know how the problem persists even when I've deleted the esp-file. Also a possible fix to my problem would be appriciated.
