When I converted my 1.17.1 Minecraft world, I tried to look to Y 0 to see if it's generating bedrock or not.
Then suddenly I saw this.
It's probably because of the one part is generated on 1.17.1, one part on 1.18. But I am not sure.
This is not looking so important, but it looks funny
Observed Results:
There was a half-amethyst geode and half-cave.
Expected Results:
There would be a full geode and cave.
Example world & coordinates
World: direct link (from MC-241216)
/execute in minecraft:overworld run tp @s -132.36 -3.43 69.77 680.46 20.84
The cave cannot be full, because it would affect already generated world above Y = 0;
The amethyst geode problem could be solved by not generating them above Y = -10 in worlds converted from 1.17.1
