Did you look at the skybox and ask, "Why does the water stop over there" or "Why in the world are there mountains in the distance, we are on an oilrig. Ask no more, I have fixed at least one of those issues. now instead of asking those questions, you ask, "Why does that fog over there look so weird" or "Why is there a square of water around the oilrig that has a weird glare on it" or "Why are there mountains behind the fog on the skybox." These questions are valid, but sometimes you just have to ignore things for the sake of it.
Note - I'm pretty sure I didn't fix the water being made an entity to try it out, but it doesn't really matter, and I've already fully packed the update and am just now remembering it. I don't think mountain did anything this update except give a thumbs up.
