ah i see what happened
{0} is the bradleytier that will change the name if changed in cfg
{1} is the location
so in your case you change the {0} into {1}
"BradVanilla": "A <color=#EC1349>{0}</color> Bradley has spawned around <color=#EC1349>{1}</color>",
"BradEasy": "A <color=green>{0}</color> Bradley has spawned around <color=green>{1}</color>",
"BradMedium": "A <color=purple>{0}</color> Bradley has spawned around <color=blue>{1}</color>",
"BradHard": "A <color=red>{0}</color> Bradley has spawned around <color=red>{1}</color>",
"BradNightmare": "A <color=yellow>{0}</color> Bradley has spawned around <color=yellow>{1}</color>",
section from cfg
"Tier Names": {
"Vanilla": "Normal",
"Easy": "Noob",
"Medium": "Intermediate",
"Hard": "Tough",
"Nightmare": "Zombie"
},
the names above will change in the message from language file {0} without the need to edit the language file to change the names
