I thought I have followed the Step 2.2.9 procedure for installing the AmidianBorn Content Addon. Though I am not sure where I went wrong with it.
I downloaded it through Mod Manager, manually installed it. I unchecked the AmidianBorn_ContentAddon.esp just below the textures folder and above the directions text file. I clicked the arrow next to Improved closefaced Helmets and moved the aMidianBorn_ContentAddon.esp from that folder into the <data>.
I have been following the Step Extended and ignored the meta rule instructions as per the Step instructions. I am now about to make my Brashed Patched. I can not find the aMidianBorn_ContentAddon.esp file in WyreBrash within the Mods Tab or in Loot as an option to add a Meta Rule.
Have I been reading the instructions wrong and how do I go about fixing this?
