This is not much of an issue, but it's still weird. The picture is fairly self-explanatory, but for context, this is a stump with a log that generated with the log part above a river.
How to reproduce:
1. Make a world with the seed -4934109026671495692
2. Go to the coordinates X: 496 Y: 67 Z: -283
3. Behold the floating log. I'm pretty sure one of the splash messages is, and I quote, "DON'T LEAVE TREES FLOATING!!!", so an alternate fix to this bug is just to remove that message.
Edit:
Apparently there's another one in the same world? It's somewhat less broken from one way of looking at it, but it still looks really weird, since it's on top of a piece of grass. The coordinates for that are 461 81 -330.
Thank you for your report!
After consideration, the issue is being closed as Won't Fix.
Please note that this is not the same as Working as Intended, as this bug report correctly describes behavior in the game that might not be the intended or desirable behavior, but it will not be fixed right now.
