I am creating a a ghost sprite that will mimic the main sprite after 10 seconds of the game. I am storing the users movements in a List<string> and i am using a foreach loop to run the movements. The problem is when i run through the game by adding breakpoints the movements are being added to the List<string> but when the foreach runs it shows that the list has nothing in it. Why does it do that? How can i fix it?

this is what i have:

public List<string> ghostMovements = new List<string>();

    public void UpdateGhost(float scalingFactor, int[,] map)
    {

        // At this foreach, ghostMovements has nothing in it
        foreach (string s in ghostMovements)
        {
            // current position of the ghost on the tiles
            int mapX = (int)(ghostPostition.X / scalingFactor);
            int mapY = (int)(ghostPostition.Y / scalingFactor);


            if (s == "left")
            {
                switch (ghostDirection)
                {
                    case ghostFacingUp:
                        angle = 1.6f;
                        ghostDirection = ghostFacingRight;
                        Program.form.direction = "";
                        break;

                    case ghostFacingRight:
                        angle = 3.15f;
                        ghostDirection = ghostFacingDown;
                        Program.form.direction = "";
                        break;

                    case ghostFacingDown:
                        angle = -1.6f;
                        ghostDirection = ghostFacingLeft;
                        Program.form.direction = "";
                        break;

                    case ghostFacingLeft:
                        angle = 0.0f;
                        ghostDirection = ghostFacingUp;
                        Program.form.direction = "";
                        break;

                }
            }
        }   
    }

    // The movement is captured here and added to the list
    public void captureMovement()
    {
        ghostMovements.Add(Program.form.direction);
    }
