As title says I have a follower mod installed and wanted to change it's body to 3ba and use my skin textures, but after I do that the NPC disappears and it's there before I make any changes. The npc has an ID for me to spawn it but after I do it's like it does nothing. I did it for a similar mod and it worked out fine so not really sure what exactly i'm doing wrong this time.
