Client-side Forge mod for Minecraft 1.20.1 that patches critical third-party mod crashes at runtime with Mixins, without modifying original JARs.
Description
CrossFixes
CrossFixes is a client-side Minecraft Forge mod for 1.20.1 that patches critical crashes caused by bugs in third-party mods.
It uses the Mixin system to inject fixes at runtime without modifying or replacing the original mod JARs.
Purpose
Some popular mods ship with null-pointer bugs that can crash your game under certain conditions — loading a GUI before the world is ready, or interacting with a broken multiblock structure.
CrossFixes silently intercepts these crash points and returns safe fallback values instead of letting the game throw a NullPointerException.
Fixes
GeckoLib 4.8.3+
- Crashes the client when any animated item is rendered in a GUI (e.g. FancyMenu) before a world is loaded.
MagiChem 0.5.1+
- Crashes when right-clicking a Mirror Labyrinth Router whose multiblock structure is broken or incomplete.
Requirements
| Dependency | Version |
|---|---|
| Minecraft | 1.20.1 |
| Forge | 47.4.18+ |
Each fix is only active if the corresponding mod is present. CrossFixes does nothing if neither of the affected mods is installed.
Installation
- Download the latest CrossFixes JAR from the Files tab.
- Place it in your
mods/folder alongside the affected mods. - Launch the game — no configuration required.
Compatibility
- Side: Client-side only (safe to use on servers without requiring all clients to have it).
- Other mods: CrossFixes does not touch any gameplay mechanics and is compatible with any modpack that includes GeckoLib or MagiChem.
