If you've ever loaded up a modpack only to be greeted by a cryptic "Not enough data available" crash, you already know the frustration that Night Config Fixes Mod was built to solve. Created by Fuzs, this utility mod patches a long-standing bug in the Night Config library that causes blank or corrupted config files to crash Minecraft entirely. With over 3.7 million downloads, it has become an essential safety net for heavily modded setups — especially popular modpacks like Better Minecraft that are prone to this exact issue.
Key Features
- Crash prevention for blank configs — Catches the "Not enough data available" parsing error before it brings down your game, automatically recreating the affected config from default values instead of crashing to desktop.
- Modpack stability — Particularly useful for large modpacks like Better Minecraft that frequently trigger config corruption, keeping your sessions running smoothly without manual file fixes.
- Global server config directory — Allows server configurations to be generated in a single global directory rather than duplicated per world, simplifying server management across multiple worlds.

FAQ
What does Night Config Fixes Mod actually do?
It intercepts the "Not enough data available" error that occurs when a config file becomes blank or corrupted. Instead of letting Minecraft crash, the mod catches the error and regenerates the config using default values so you can keep playing.
Do I need Night Config Fixes for modpacks like Better Minecraft?
It is highly recommended. Better Minecraft and similar large modpacks are known to trigger this config parsing issue frequently, and this mod prevents those crashes from disrupting your gameplay.
Does Night Config Fixes work on servers?
Yes, it works on both client and server. On servers, it also offers the option to store configs in a global directory instead of generating separate config files for each world.
