Yes, I performed a search before posting. Here's the bug; while exploring a cave (Low Y coordinate) I placed a bucket of water on the stone while walking down at the same time, & the water disappeared. The water bucket in my hot bar did update from a full water bucket to an empty bucket after placing the water. But the water itself didn't appear on the stone. I walked over that empty spot and there were no water physics present. I tried reloading the game (which always works). However, I was still left with an empty bucket and no water placed. This is very rare. I'm not a programmer but my "guess" is I placed the water right on the same frame as something else in the game is being rendered, at the same time. Or something under those lines.
