While this is perfectly fine, I would recommend editing CC_ConfigOverride.js (location in the attached screenshot). Keep a copy of the ConfigOverride file as per your settings and you won't need to edit it every time there's a new update in the mod (unless of course some key variable you've edited suddenly changes...which is rare)edit CC_Config.js with Notepad++ or notepad (location => Karryn's Prison\www\mods\)
scroll down or search
