This problem only happens on one character, the others are all fine and on this character it only seems to happen inside solitude (But not inside the building inside solitude). NPC's start to walk but after walking about a foot or two they kind of spring back to their previous spot, pause for a seconds and try again. As I said its only on this one character while inside solitude. Inside a building inside solitude or outside of solitude everyone seems to be fine. Even whiterun, windhelm, riften and markath seem unaffected. Doesn't seem like its a mod issue cause it only affects this one character and I have reinstalling skyrim recently after reformatting my HDD and it still have the problem after a clean install. Is there a way to fix this So I can finish my business in solitude?
