Oh boy, you should see this!
I had never seen those before. That’s very cool.
I read it. The world I took this photo on is a vanilla 1x world that I created a few days ago.
That happened to me before on my single player server, I even made a house on one after I took the water out of the area.
What’s the world size? I suspect 1/16th - weird things happen with that size.
Then again - could be just the Mountainous setting withe More Lakes.
Wow, I’m very surprised as I’ve never seen that happen on a Vanilla world.
Very rare find indeed!
