Being specific, after cleaning an 8x8 wheat farm with a water bucket that gathers all items at one block. This happens after the player replanted the wheat seeds. Near the edge where water drops some force prevents the player from walking back. towards the direction, water was flowing from.The player can run and jump past it. If walking from the other side, where the water originated, towards where the water drains, the force will start to take effect once the player is in the affected area.
