Round Loop Problem?...

I am stuck in some kind of a loop and i have no idea what is the problem. I even comented all the code step by step and i dont see why it is acting so wierd.

Code:

 LobbyMaster lm;           
 Scoreboard scoreboard;        
 public GameObject roundStats;        
 public GameObject teamStats;        
 public GameObject scoreboardGO;        
 public Text roundText;        
 public Text infoText;        
 public int numOfRounds;        
 private int round = 0;        
 private bool seeking;        

 void Start () {
     try { lm = GameObject.Find("Lobby Master").GetComponent<LobbyMaster>(); }
     catch { lm = GameObject.Find("Lobby Master_b").GetComponent<LobbyMaster>(); }
     scoreboard = GetComponent<Scoreboard>();

     NewRound();
 }

 void Update()
 {
     //for every team
     for (int i = 0; i < lm.numOfTeams; i++)
     {
         //if they have 5 points before the time ends
         if (lm.teams[i].points >= 5 && lm.curTime > 0)
         {
             if (round <= numOfRounds)
             {
                 lm.curTime = -1;
                 StartCoroutine(RoundEnd());
             }
             //last round -> end game
             else
             {
                 EndGame();
             }
         }
         //if they didnt get 5 points in time
         else if (lm.curTime == 0)
         {
             lm.curTime = -1;
             StartCoroutine(RoundEnd());
         }
     }
 }

 IEnumerator RoundEnd()
 {
     Debug.Log("Round End");
     //show round ending screen and hide sidebar
     roundStats.SetActive(true);
     scoreboardGO.SetActive(false);
     // spawn in all the teams on the result screen
     for (int i = 0; i < lm.numOfTeams; i++)
     {
         GameObject scoreGO = (GameObject)Instantiate(teamStats, new Vector2(0, 0), Quaternion.identity);
         scoreGO.transform.SetParent(roundStats.transform.FindChild("Won"));
         scoreGO.name = "Team Stats" + i;
         scoreGO.GetComponent<RectTransform>().localPosition = new Vector3(roundStats.GetComponent<RectTransform>().sizeDelta.x / 2, -60 * i);
         scoreGO.GetComponent<Text>().text = lm.teams[i].color + " team - " + lm.teams[i].points.ToString();
         scoreGO.GetComponent<Text>().color = lm.colors[i];
         yield return new WaitForSeconds(0.1f);
     }
     yield return new WaitForSeconds(2);
     //after 2 seconds destroy spawned in teams
     for (int i = 0; i < lm.numOfTeams; i++)
     {
         GameObject ts = GameObject.Find("HUD").transform.GetChild(1).GetChild(0).Find("Team Stats" + i).gameObject;
         if (ts)
         {
             Destroy(ts);
         }
     }
     //show sidebar and hide round ending screen
     roundStats.SetActive(false);
     scoreboardGO.SetActive(true);

     NewRound();
 }

 void NewRound()
 {
     Debug.Log("New Round");
     roundText.text = "Round: " + round;
     round++;
     seeking = false;
     //reset points
     for (int i = 0; i < lm.numOfTeams; i++)
     {
         lm.teams[i].points = 0;
     }
     //reset scoreboard results
     foreach (Text curText in scoreboard.results)
     {
         curText.text = "0";
     }
     ResetPlayers();
     //set random setter
     for (int i = 0; i < lm.numOfTeams; i++)
     {
         int randomSetter = Random.Range(0, lm.teams[i].players.Count);
         //lm.teams[i].players[i].GetComponent<Player>().IsSetter = true;

     while (lm.curTime > 0)
     {

         int seconds = lm.curTime - minutes * 60;
         lm.curTime--;

         yield return new WaitForSeconds(1);
     }

     //when time runs out set down remaining items if they have any left
     for (int i = 0; i < lm.numOfTeams; i++)
     {
         for (int y = 0; y < lm.teams[i].players.Count; y++)
         {
             if (lm.teams[i].players[y].GetComponent<Player>().itemsLeft > 0)
             {
                 // set down remaining items
             }
         }
     }
     ResetPlayers();
     //display text
     StartCoroutine(SetInfoText("Start searching", 2f));
     seeking = true;

     //time for searching
     lm.curTime = lm.roundTime;
     while (lm.curTime > 0)
     {
         int minutes = lm.curTime / 60;
         int seconds = lm.curTime - minutes * 60;
         lm.curTime--;
         scoreboard.timer.text = minutes + " : " + seconds;
         yield return new WaitForSeconds(1);
     }
 }

 void EndGame()
 {
     //result screen
 }

 void ResetPlayers()
 {
     //move players to their teams spawn
 }

 IEnumerator SetInfoText(string text, float delay)
 {
     infoText.text = text;
     infoText.gameObject.SetActive(true);

 //Update -> RoundEnd -> NewRound -> GameLoop

So basicly it does this: ...Because it happens so quickly and its a lot of code at once i cant exactly tell you what is wrong D:

If you need some more explanation feel free to ask.
