It began when I was trying to get my follower to reach a coin purse in a spike pit, my follower refused so I gave up and tried to exit out of the follower action menu, though it did not disappear it remains after I reloaded a save, restarted and when I created a new character after deleting my previous one. This makes it impossible for me to enter dungeons and speak with NPC's although it does not seem to have affected my previous characters.

If i am right, you saying every time you load a save after that the "follower action menu" stays in front of you ????
