EndGame after the first bowl every time!

[Rrawrr1]

Hi, guys!
I’m passing now Bowl Master section, and game is almost finished (I’ve passed to the Epic TDD challenge) but I still have one serious problem.
It is appeared few lectures before, when I did the Bowl method in ActionMaster script, which automatically controls all these Tidy and Reset actions.
I’ve unsuccessfully tried to solve it and finally decided to go forward, expecting to find a solution later, but I didn’t find it.

Problem is that after I do the very first bowl, I get an EndGame statement.
Spoiler does Tidy, Tidy, Reset then EndGame (which is for now just a message in console). It looks like game goes through all the bowls from 1 to 21 and gives me EndGame statement in the end.

I copied the code of ActionMaster from the ActionMasterOld script from the added to the course archive, but problem is still there. So I ask you guys for help. Do you have any ideas where is the problem?

public class ActionMaster
{
public enum Action {Tidy,Reset,EndTurn,EndGame};

private int[] bowls = new int[21]; 
private int bowl = 1;

public static Action NextAction (List<int> pinFalls)
{
    ActionMaster am = new ActionMaster();
    Action currentAction = new Action();

    foreach (int pinFall in pinFalls)
    {
        currentAction = am.Bowl(pinFall); 
    }

    return currentAction;
}

private Action Bowl(int pins)
{
    if (pins < 0 || pins > 10) { throw new UnityException("Invalid pins"); }

    bowls[bowl - 1] = pins;
    Debug.Log(bowl);


    if (bowl == 21)
    {
        return Action.EndGame;
    }

    // Handle last-frame special cases
    if (bowl >= 19 && pins == 10)
    {
        bowl++;
        return Action.Reset;
    }
    else if (bowl == 20)
    {
        bowl++;
        if (bowls[19 - 1] == 10 && bowls[20 - 1] == 0)
        {
            return Action.Tidy;
        }
        else if (bowls[19 - 1] + bowls[20 - 1] == 10)
        {
            return Action.Reset;
        }
        else if (Ball21Awarded())
        {
            return Action.Tidy;
        }
        else
        {
            return Action.EndGame;
        }
    }

    if (bowl % 2 != 0)
    { // First bowl of frame
        if (pins == 10)
        {
            bowl += 2;
            return Action.EndTurn;
        }
        else
        {
            bowl += 1;
            return Action.Tidy;
        }
    }
    else if (bowl % 2 == 0)
    { // Second bowl of frame
        bowl += 1;
        return Action.EndTurn;
    }

    throw new UnityException("Not sure what action to return!");
}

private bool Ball21Awarded()
{
    return (bowls [19 - 1] + bowls[20 - 1] >= 10); 
}

}

There are messages in console of Debug.Log(bowl).
I think here should be only one number of current bowl.

Fortunately, I found why it happened. Looked through all my scripts and found that at one moment earlier in PinCounter I put self-maded method:

void CheckStanding() {

        Invoke("PinsHaveSettled", 3f);
    }

Instead of Ben’s:

void UpdateStandingCountAndSettle (){

		int currentStanding = CountStanding ();

		if (currentStanding != lastStandingCount) {
			lastChangeTime = Time.time;
			lastStandingCount = currentStanding;
			return;
		}
		
		float settleTime = 3f;  // How long to wait to consider pins settled
		if ((Time.time - lastChangeTime) > settleTime) { // If last change > 3s ago
			PinsHaveSettled();
		}
		
	}

I was thinking to try how it works and actually tried Facepalm but forgot to change it back.
