There was always a bug with blocks placed on top layer of water on PC/Android. - if the block is placed over water, you fall through the block.
So a few days ago I exploded a water bomb in my world with the new weather machine.
The water stayed in the air and you can swim through it BUT:
1. all blocks placed on water placed after machine is turned on are walk through
2. when blocks are removed, water is left behind them.
So basically on PC/android you can't use a Butler to move water, nor can you shape water with blocks :(@mikelarence
