TaCZ Runtime Compat
Fixes custom TaCZ gun packs so they work properly in large modpacks without crashing.
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

- Ensures custom TaCZ guns load properly

How to use:
