Stuck while solving a Coroutine problem

Hey guys, I’ve been stuck on this problem for almost two days, and I can’t seem to be able to figure it out on my own, so I would really appreciate your help. First of all, here’s my code.

     function Update () 
 {
 
     if ((takeTurns.machineTurn == true)&&(takeTurns.playerTurn == false))
         JustACoroutine();
 }
 
 
     function JustACoroutine()
     {
         yield WaitForSeconds(5);
         
         for (var f = 0; f <50; f++)
         {
             for (var w = 0; w < 50; w++)
             {
                 if (createBricks.globalArray[w,f,0] != null)
                 {
                     if(createBricks.globalArray[w,f,0].gameObject.GetComponent(Rigidbody) != null)
                     {
                         Destroy(createBricks.globalArray[w,f,0].gameObject);
                     }
                 }
             }
         }
         allMurdered = true;
     }

The problem is, allMurdered remains true indefinitely. That is, long after takeTurns.playerTurn had been switched to true and takeTurns.machineTurn to false. Here’s the bit of code that does that:

 function LookForClicks()
 {
     if (createBricks.turnClicks == 4)
     {
         playerTurn = false;
         machineTurn = true;
         createBricks.turnClicks = 0;
         yield WaitForSeconds(6);
         murderer.allMurdered = false;
         playerTurn = true;
         machineTurn = false;
     
     }
 }

I believe that the problem lies in having two coroutines running simultaneously, but then I don’t understand them very well and can’t quite put my hand on the flawed part.

Again, any help at all very appreciated.
