Fix for Broken Iron Barrels

IMPORTANT: This is a datapack! You need to add it to your world's datapack folder or use an automatic loader such as OpenLoader or Paxi.

This datapack fixes a long-standing issue in the Iron Chests Restocked modification - iron barrels cannot be mined normally. This bug existed for over two years and forced players to either use explosives to destroy the barrels or spend enormous amounts of time trying to mine them.

Installation: Download the ZIP archive and place it in your world's datapack folder. If you have OpenLoader or Paxi installed, you can place the datapack in the appropriate data folder of these loaders.
