In a ravine I was trying to grab a water source from a waterfall that naturally spawned there, and I swam into the water source. I don't know exactly what happened, but I went in and out of sprint underwater, and I right-clicked. The empty bucket I had been holding filled, but the water source had not been removed. There was not an infinite water source, only one water source. Then when I go to place it down, water flashes where I placed it for a fraction of a second and then disappears. My bucket changed from full to empty at the same time also.
