Wrong Water drop animation after having fell on the floor in Elysium Mine

There are some water drops falling from the top of the level 2 and level 3 of Elysium Mine. After the water drops fell on the floor or water surface, there are some wrong animations. You will see the water drops which already fell down travelling horizontally on the floor or water surface for a long distance. And, this happens a lot if you pay attention to them.
