My characters won't move

I have a big problem with my game. In wenshaganaw my main character move but my companions are not moving anymore like before. They don't follow and just appear again when i'm talking to others pnj.
Where is the problem ?

Thank you

Have you tried to fast travel and try again?

Hello @shualua
Is this bug still occuring right now?
Did you notice a pattern in the way they stopped moving (was it after an important cutscene or after triggering a specific action)?
Thank you and have a great one!
