when picking up water with a bucket, sometimes the water does not get picked up but the bucket still gets filled, when attempting to place the water in this glitched bucket the water does not place at all. The only way to get the water back is to pick it back up from the original water placement (sorry if this is a bit confusing, the glitch is very confusing too). This makes things like MLG waters and the ender dragon fight a lot harder, making me usually have to pack 2 water buckets and making an infinite water source in the end to never run out of water. Usually this happens when moving the camera really fast while picking up water.

steps to reproduce:

1. place water
2. move camera really fast trying to pick it up
3. if those don't work try it multiple times until it does
