Garda NPCs have not reset properly to their default places after they move anywhere. This happens when you take the guard NPCs as a Garda or if they just move to yell at people for having OCR that's too high.
Edit: For example, the garda NPCs at the gate will just stand there throughout their shifts. They moved to yell at someone for high OCR and remained in the shouting pose all day until a guard player commanded them back in their spots. To which, they just stood there and didn't move.
