Quite new to modding Skyrim. Due to internet issues i am having to manually download them onto my Desktop then import them into NMM. I have imported two companion mods and one pet vendor mod and the NPCs will not interact with me. Their is head movement and they are tracking me but when I attempt to interact I get nothing. As it has happened with three different mods I know the fault is my own and I was wondering if anyone has any advice to solve this issue. Thank you in advance for you help and I apologize if a similar thread has already been posted.
