Vanishing Water

According to the clip, newly poured water is compressing into 1000 kg per tile. You should take note the amount of water for each tile in the reservoir before adding water and then check the amount again when water level in the reservoir is stable. 

I can see what you mean by the clip. In the saves I had water up to the airflow tile. The cooling room was a triangle with the bottom right incline of the tank as it’s hypotenuse . I think even with the change in tank size I still lost water. I will double check when I get home. Thanks for the input.
