Lake Crash Fix
by Lunade
Lake Crash Fix stops lake features from crashing world generation on Minecraft 1.21 and 1.21.1, and is a server-side only Fabric and Quilt mod.
What it does
Lake features crashed during world generation after Mojang changed how chunks are handled in 1.21. This mod corrects that handling so lakes generate without the crash. The change is limited to the server, so players connecting to a server running it need nothing installed. Builds exist for Fabric and Quilt, covering game versions 1.21 – 1.21.1. It is open source under the MIT License.

What the author says
In 1.21, Mojang made slight changes to world generation to improve performance. Specifically, a change with how chunks are handled. This causes the Lake feature to crash upon worldgen, as it checks in these now unloaded chunks for the biome, in order to determine if Water it places shall freeze or not.
