One of the ugliest things in all of Skyrim is the water LOD block bug that everyone seems to have, more or less, making it quite a pain to be on top of mountains looking over the ocean. I'm sure someone who knows LOD can explain it better.

I haven't seen any mod or even attempt to fix it. Maybe it's time for that now?
It would be interesting to hear if this issue is also present in other worldspace mods, like Falskaar or Hoddminir.
