A while ago in my play-through I encountered a glitch with Farkas where he would keep talking to me while he followed me. I managed to fix this following a google search. However even after I told him to leave me he continued to follow me.
It didn't bother me at the time but now I have a problem. While chasing the Daedric artefacts I'm at the one now where I need to sacrifice someone. However, I can't get rid of farkas to make anyone else follow me so I can sacrifice them, the only dialogue option that comes up is the heavy armor training. And if I ask someone else to join they tell me I already have a follower....
So, is there a way I can get rid of farkas even though there's no option or am I doomed from getting completing this quest and getting the trophy?
