If I place a solid block with a button on one of the vertical faces, then using that same face place water from a bucket. The water flows out like normal, but if I try and pick the source block back up in the bucket it disappears, but the water stays flowing. The bucket also remains empty. In order to pick the water back up I have to break the solid block or the button then pick up the water.
