Sims 3 Strange water animation

Having just downloaded generations onward and applying the fixes as suggested, I note that when I go ingame and zoom to a playable level, I get a strange water animation at the bottom of my screen like a sprinkler animation or some such thing. I was wondering if anyone else had this problem or better yet, knew how to fix it.
