Platform
When using the minecraft:lake feature type and placing water as a fluid, the chunk generation thread crashes because of a call to WorldGenLevel.getBiome.
To reproduce
- Setup a single biome world with Plains as the selected biome
- Use either the lake_crash.zip
or lake_no_crash.zip datapack
The only difference between lake_crash and lake_no_crash is that lake_no_crash uses lava instead of water in the lake configured feature.
Expected results
The game allows you to use the minecraft:lake feature with water.
Observed results
When using lake_crash, sometimes it says "Server closed" and other times it hangs on the loading screen.
