Why are you using a 1.17 snapshot? You should upgrade to the full release 1.17.1 before trying to go to 1.18 pre release...
Bummer, looks like you're right.
Note: I will add a world download once I have it uploaded to a hosting site.
Added pre release 6 screenshots in brand new copy of seed. Mostly fixed but still looks very strange. Water seems to just be coming from mid air with no blocks under or on top of it.
Yes, correct. The sand should be considered when blending an old sand floor with a new one.
Not a new world, but freshly generated terrain inside an old world.
Added more information.
I see this was marked as resolved. Would a zip of my affected world still be helpful?
Note: Trying this in the same world, but in pre release 4, the chunks generate and it does not crash.
I did. I have been updating every snapshot since I think 21w39a with this world. I skipped 21w44a due to some bugs I didn’t want to deal with with the bedrock not generating, so this world came from 21w43a—>1.18pre1
I also have this issue and have reported it as a bug. Ampolive has also commented on my issue that it’s a duplicate with the issue they linked. It is a separate issue from the one they keep linking. Ampolive please stop linking that issue.
This is not a duplicate issue with that linked issue. Completely different.
This is normal
