Water not watering?

I have no clue how to describe it but basically fish would flop on the ground in the water and die as if they were on land, you would take fall damage when you touched the ground in the water.

Are you sure this is an Alternate Current issue, and not another mod? Alternate Current doesn't modify or even reference any code related to water at all. I do not see how it could cause such a bug.
