OPAC Fixes is a Fabric mod for Minecraft 1.20.1 servers using Open Parties and Claims. It reinforces protected claims when other mods introduce custom explosions or block interactions that can evade standard protection checks.
Its compatibility patches cover Mutant Monsters explosions, Supplementaries Red Merchant bombs, and Botania’s Ring of Loki blueprints, helping prevent unwanted damage, entity harm, block placement, or block breaking inside claimed areas. The fixes load conditionally only when supported mods are present, keeping modpacks tidy. For our BoxToPlay community, it is a focused server utility that makes protected builds safer in complex modded gameplay.
