OPAC Fixes
A Fabric Minecraft mod that provides claim protection compatibility fixes for Open Parties and Claims (OPAC) when used alongside other popular mods.
Overview
Some mods implement custom explosion or block placement/breaking mechanics that bypass standard Fabric event listeners, allowing players or mobs to bypass OPAC claims protection. This mod surgically intercepts these behaviors to ensure that claims remain protected.
Features
- Mutant Monsters: Prevents mutated explosions (e.g. Mutant Creepers) from destroying blocks and harming entities inside protected claims.
- Supplementaries: Prevents Red Merchants' bombs from bypass griefing blocks and entities in protected claims.
- Botania: Prevents the Ring of Loki from bypass-placing or bypass-breaking blocks inside protected claims using blueprints.
- Conditional Loading: Compatibility mixins for Mutant Monsters, Supplementaries, and Botania only load if the respective mods are detected at runtime.
Installation
- Ensure you have Fabric Loader and Fabric API installed for Minecraft 1.20.1.
- Requires Open Parties and Claims (OPAC) to be present.
- Drop this mod into your mods folder.

With Millida Launcher
Install Millida Launcher
The launcher is free: download it at millida.net/launcher and sign in with any nickname.
Click “Install” on this page
The launcher opens and installs the mod for Minecraft 1.20.1–1.20.6 on Fabric automatically, together with its dependencies: Mutant Monsters, Open Parties and Claims.
Launch the game
A profile with it appears in the launcher: click “Play”.
Manually
Install Fabric
The loader must match the game version of the mod file, for example Minecraft 1.20.6. After installing it, a separate profile appears in your launcher.
Download the file for your version
In the version list above, pick the file opac_fixes-1.1.3.jar (116 KB) for your game version.
Put it in the mods folder
The folder is inside .minecraft (Windows: %appdata%\.minecraft\mods). If it does not exist, create it. Required dependencies go there too: Mutant Monsters, Open Parties and Claims.
Launch the loader profile
Open “Mods” in the main menu: OPAC-Fixes should be in the list.
On a server
A server on Fabric
The mod only works on a server with the same loader and game version, for example 1.20.6.
File goes into the server’s mods folder
Stop the server, put the mod file into the mods folder and start the server again.
Or use the “To hosting” button
On Millida Hosting, the button at the top of the page uploads the file to your server and restarts it for you.
Minecraft 1.20.6 runs on Java 21: with a different Java version the game may close right after launch.
