I installed Vanilla Hammers and I got a buttload of extra hammers and there is no config to disable anything or any config I can find.

I'm not sure if there is an error or not as it does not Match the Curse Page description.

Thanks.

Logs, please! Vanilla Hammers has a config file named vanilla-hammers.json in your config folder. The second line in this config file, enableExtraMaterials, is what you are looking for.
