Is it possible to get the position of an Instigator?

Try this

DoSwaglines(DamageResult : damage_result)<suspends> : void =
        Time := 0.001
        if(Instigator := DamageResult.Instigator?):
            if(Agent := Instigator.GetInstigatorAgent[]):
                if(F_Char := Agent.GetFortCharacter[]):
                    F_Char_Rotation := F_Char.GetTransform().Rotation # or F_Char.GetViewRotation()
                    F_Char_Location := F_Char.GetTransform().Translation

                    Follower_Prop.MoveTo(F_Char_Location, F_Char_Rotation, Time)
