What happened?

Im not sure if im right but in 2 days of exploring the caves and surfaces in search of granite i didnt find none.
About areas. I found some areas at the north from the spawn are non connected chunks and they have the stone walls .

Version

1.0.2

Provide the log

No response

Caused by Chunky pregeneration, will not be used next time.

Oh no. Please not.

:( Yes im scared of wipe xd

Can confirm. Cannot confirm theres no diorite present, i did some search with WorldEdit and found a lot.

OH well alright so its rare as i see

Can you say something about the chunk borders?

@TheRanker

Diorite is present in worlds.

1a. If using datapacks (end in .zip), put them all in the world/datapacks folder.
1b. If using mods (end in .jar), put them all in the mods folder.

2. Start your server, wait for it to load, then stop it.

3a. [Terralith only] Inside the world folder, delete the entire region folder, and nothing else.
3b. [Incendium/Amplified Nether only] Inside the nether folder, delete the entire region folder, and nothing else. On Spigot/Paper, the nether folder is world_the_nether, and it's world/DIM-1 on Fabric/Vanilla.

4. Start your server again, and enjoy!
   There is a bug upstream in vanilla MC that causes it to not respect custom world gen on first load.
