When items are put in falling water, they float up as if it's normal stationary water. This doesn't make much sense, and also breaks my current crop farm's mechanics. I used this design: https://youtu.be/FuLBnF8V-Sk
The crops are supposed to be transported through many down-flows of water, but with the current water physics the crops just pile up on each level and don't move anywhere.
To replicate, put a water source in mid-air or somewhere high to make the water flow downwards. Then throw some items into the water and watch as the items float against gravity and the current.
I get that Minecraft is just a game and it doesn't need to follow physics, but this issue in BE doesn't occur in Java. Items in the Java still move downwards with the water current in the latest snapshots. The items only float if the water is stationary.
