When you try to play a world on older versions the chunks will generate new!
What I expected to happen was...:
To find the world withe chunk corruption but withe same generated stuff and my builds.
What actually happened was...:
The World generated withe the same seed but in the 1.17.1 intead of the 1.18.
Steps to Reproduce:
1. Create a world in the 1.18
2. Load some chunks and leave
3. Then join withe the 1.17.1 and choose "Copy 'n load" .
4.Have fun withe your fresh world.
