I tried to change the Earthbore Gauntlet's config to make it a stronger weapon, but the changes were not applied. I know the config is correct because the Axe of a Thousand Metals correctly changed it's stats to what I specified. I saw a changelog regarding mob health and damage, so it could be related.

I am currently running mowziesmobs-1.5.25.jar and used the /config command to directly access the config file.
