Lake Crash Fix
In Minecraft version 1.21, Mojang developers made certain changes to world generation to improve performance. Specifically, they altered the principles of chunk handling.
These changes led to an error where the lake generation feature causes crashes during world creation. The problem occurs because the system attempts to check the biome in chunks that have already been unloaded from memory, in order to determine whether the placed water should freeze.
This mod solves this problem in a simple way - it removes this check, which completely eliminates crashes during lake generation.
