Information

Minecraft version: 1.16.1
Forge version: 32.0.24
Environment: Singleplayer

Mod name: The Vanilla Experience modpack
Mod version: 1.16-2.3

Description

Created new world on the modpack and was stuck for couple minutes on chunkless world.
Disabling villagespawnpoint removed the problem and worlds were created without issues.

Do you have any logs to share from successfully reproducing this?

It could be that there are no villages within 1.5 km (1500 blocks) of the world's origin and/or /locate Village was unable to find anything, hence world generation being stuck on choosing player spawn point.

I've updated quite a few mods in the pack, improved code and made them more efficient. I've just played the pack for an hour with 3G of RAM and haven't had any issues come up. I'm pretty certain the problem is fixed in thevanillaexperience_1.16.3-2.11. Thanks for letting me know and sorry for the inconvenience!
