About this Mod

In small or simple mod setups, custom guns usually work fine. However, in large modpacks, you may encounter errors like:

"net.minecraft.resourceLocationException: Non [a-z0-9/._-] character in path of location: tacz:gun"

This happens because some custom gun packs contain invalid resource paths that break under stricter loading conditions.

This mod automatically fixes those issues at runtime, allowing your custom TaCZ gun packs to load and function correctly even in large modpacks.

  • Fixes invalid resource path errors
  • Prevents crashes in large modpacks
  • Ensures custom TaCZ guns load properly
  • Works automatically — no setup needed

Requirements:

How to use:

  1. Install TaCZ and TaCZ Pack Upgrader
  2. Put your custom gun packs into the "tacz" folder
  3. Install this mod
  4. Launch the game — done!

This mod does not add any content. It only ensures your custom guns work smoothly, especially in large modpacks.
