Sorry about the duplicate. However this one has a Weird and very technical title so I didn't find it in my search so here is my information in 21w40a.
"This one is funny one. I love it but it's clearly a bug. Haha! 😆
The Ocean is a chunk or two wide but since the generation is a little higher than normal the water did not generate."
I don't like the moving feature, well at least the side to side, the up and down is reasonable.
Not a fan of it moving side to side though, up and down is a little more reasonable I am fine with that.
Thanks for the information 🙂
screenshots taken at 19 chunk render distance.
Everything is up to date.
Thanks for letting me know. However, with an oddly long and technical title I see why I couldn't find it at first. 😛Â
